Many large-scale operations require replica databases before they apply any form of data anonymization technique. Individuals, on the other hand, can <strong>anonymize their online data using a VPN with powerful encryption<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a better understanding of how it works, let\u2019s take a deep dive into a few of the most common methods used for data anonymization.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<a style=\"text-decoration: none;\" href=\"https:\/\/www.privateinternetaccess.com\/buy-vpn-online?conversionpoint=data_anonymization\"><button class=\"bg-btn-1\"> Try Private Internet Access <\/button><\/a>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"common-data\"><strong>Common Data Anonymization Methods<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Multiple forms of data anonymization exist. To include every technique, with every one of its variations could take an eternity \u2014 especially since <strong>new variations are still being developed<\/strong>. Instead, you can <strong>check out the most common data anonymization methods below<\/strong>, including some use cases and examples.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"data-masking\"><strong>Data Masking &amp; Encryption<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Masking and encryption <strong>both modify real-time data as it\u2019s being accessed<\/strong>. This is important as raw data could contain sensitive user information such as IP address, device data, location, and more. Encryption is often considered a form of data masking, but it\u2019s a separate data anonymization technique. Data masking and data encryption, though similar, have different processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Data<\/strong> <strong>masking removes specific parts of sensitive information <\/strong>from the data and replaces it with data that contains the same type of structure, but a different value. <strong>Data<\/strong> <strong>encryption, on the other hand, scrambles your data using unique algorithms<\/strong>. A cybercriminal may be able to access the data, but it\u2019s impossible to read without a key.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most affordable way for the average person to anonymize data is by using <a href=\"https:\/\/www.privateinternetaccess.com\/buy-vpn-online?conversionpoint=data_anonymization\"><strong>a VPN with high-level AES encryption<\/strong><\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Homomorphic encryption is considered better in large-scale data anonymization. <\/strong>For example, data controlled by government entities. The process encrypts information so it\u2019s unreadable, while still allowing it to be manipulated. It can be de-encrypted later, but only by the data controller.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"pseudo\"><strong>Pseudonymization<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Replacing key information with false identifiers<\/strong>, or pseudonymization, is another popular form of anonymization. As an example, 333 Bloomberg Avenue may be replaced with 345 Cherry Lane, or <strong>Fred Tuney might change to Jasper Bing<\/strong>. It\u2019s an inventive way to ensure that your sensitive data remains private. Think of authors using pen names or actors using stage names to gain more privacy \u2014 only bigger and more complex when it comes to online data.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"generalization\"><strong>Generalization<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This technique<strong> omits some of the data to make the rest of the information less identifiable<\/strong>. You can remove sensitive information like age or address, and replace the data with a randomized set or change it to \u2018unknown\u2019, without compromising the overall accuracy of the data.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s imagine Ted gets an email from a blind date service that includes the following information: Jane Bertram, 453 225th Street, Minneapolis, Minnesota, age 40. Using generalization it looks more like: Jane, 225th Street, Minnesota, (32-45). The change doesn\u2019t affect what the recipient sees, but<strong> no one else will get the information if the data is intercepted<\/strong>.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"data-swaping\"><strong>Data Swapping<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A form of data scrambling a bit like encryption, but less complicated. <strong>Data wapping shuffles attribute values, so the altered result doesn\u2019t match the original data set<\/strong>. In 1990, after several successful simulations, the <a href=\"https:\/\/www.scb.se\/contentassets\/ca21efb41fee47d293bbee5bf7be7fb3\/data-swapping-variations-on-a-theme-by-dalenius-and-reiss.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">US Census Bureau used data swapping for the decennial census<\/a>.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Census records were swapped between blocks for individuals or households that matched a specifically determined set of k variables. The (k p 1)-way marginals included matching variables and block totals that stayed the same. On the other end, marginals for tables that had other variables were subject to change at any time during tabulation.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By the 2000 census, the CB\u2019s method had shifted to ensure identifying records carrying a higher disclosure risk were included in swaps.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"perturbation\"><strong>Perturbation<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Hospitals use data perturbation methods to protect sensitive electronic health information (EHI). It\u2019s a <strong>form of data mining that adds random noise or mathematical methods (usually geometric), to create a disturbance in the database.<\/strong> The time it takes to properly implement data perturbation makes it less cost-effective for smaller companies or individuals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Perturbation can be tricky and requires precision. <strong>If the base chosen isn\u2019t proportionate to the disturbance you create, the data may not be anonymized properly<\/strong>. Worse yet, you could render the data completely unusable.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"synthetic-data\"><strong>Synthetic Data<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Creating synthetic, or fake, data is almost like playing a game of Sudoku. It <strong>requires using patterns or features from the original data set, to algorithmically create a new data set without modifying the existing data<\/strong>. The original data set remains the same, as altering it can compromise its integrity (in Sudoku it\u2019s just cheating).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The <a href=\"https:\/\/www.statice.ai\/post\/types-synthetic-data-examples-real-life-examples\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">use cases for synthetic data are expansive<\/a>, but a couple stand out as a measure of the flexibility of this anonymization technique. Amazon uses synthetic data anonymization to train the natural-language-understanding (NLU) system for Alexa, while financial services like <strong>J.P. Morgan and American Express use it to help detect fraud<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"differential\"><strong>Differential Privacy<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Using differential privacy methods <strong>includes blurring specific data points to average data sets<\/strong>. This makes it virtually impossible to de-anonymize the data because false user\/client information is reported.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Apple and Uber use this method of data anonymization<\/strong> to decrease the likelihood of user\/client information becoming publicly available on any level. To be as effective as possible,<strong> differential privacy methods must be performed by experienced professionals<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<table class=\"center\" rules=\"all\" style=\"border: 1px solid black; width: 100%; margin: auto;\">\n  <thead><tr><th colspan=\"2\" class=\"has-text-align-center\" data-align=\"center\" style=\"background-color: #6aa84f; color: none; border: none; padding: 5px;\"><strong>The Pros and Cons of Anonymization<\/strong><\/th><\/tr><\/thead> \n  <tbody><tr>\n   <td class=\"has-text-align-center\" data-align=\"center\" style=\"background-color: #93c47d; color: none; padding: 5px;\"><strong>Pros<\/strong><\/td>\n   <td class=\"has-text-align-center\" data-align=\"center\" style=\"background-color: #93c47d; color: none; padding: 5px;\"><strong>Cons<\/strong><\/td>\n  <\/tr>\n   <tr><td><p>\u2705 Less risk of data handlers exploiting user information.\n<\/p>\n <p>\u2705 Anonymization of data increases trust by giving users peace of mind.<\/p>\n<p>\u2705 Constant analysis and data supervision.<\/p>\n<p>\u2705 Prevents data loss and potential breaches.\n<\/p>\n   <\/td>\n<td><p>\u26d4 Omitting data attributes limits user insight. <\/p><p>\n     <\/p><p>\u26d4 Due to limited insight updates and patches can take longer to create.\n<\/p><p>\n  <\/p><p>\u26d4 Using the wrong form of anonymization can expose, destroy, or corrupt data.\n<\/p><p>\n    <\/p><\/td>\n  \n<\/tr><\/tbody><\/table>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"data-effective\"><strong>Is Data Anonymization Effective?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It can be. <strong>The effectiveness of data anonymization depends on the technique chosen for the job, and on whether that technique is executed correctly<\/strong>. Some methods require extreme precision. One mistake could mean that no data gets anonymized, that some data is destroyed in the process, or that the wrong data is anonymized.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It\u2019s also possible that the push to debunk data anonymization as an effective tool is \u2018Big Tech\u2019s\u2019 way of preventing total anonymization, as it would mean a loss of income from data brokers who rely on the information.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the very least, <strong>many app developers and search engines like Google would take a hit from a total anonymization approach<\/strong>. Even though Google prides itself on \u2018safely masking data\u2019, some of the data it collects isn\u2019t always anonymized \u2014 worse yet, users don\u2019t have much control over changing that.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fortunately, there\u2019s a growing response to privacy-invasive apps. For instance, the <a href=\"https:\/\/microg.org\/\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">MicroG<\/a> project aims to change Google\u2019s data collection monopoly by providing users with a privacy-friendly alternative to some of the biggest Google services.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"reverse-data\"><strong>Can You Reverse Data Anonymization<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">It is sometimes possible to reverse data anonymization, but it isn\u2019t as easy as switching a light on and off like some would have you believe. You usually need three things <strong>to reverse data anonymization:\u00a0<\/strong><\/p>\n\n\n\n<ol class=\"wp-block-list\"><li>knowledge\/training in what to look for,<\/li><li>plenty of time on your hands and<\/li><li>the datasets have to be available, publicly available, or legally up for sale.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">All these things are easy enough and companies do sell or trade anonymized data, even major ones like Experian. That said, <strong>most studies done on reversing data anonymization don\u2019t take human error into account<\/strong>. This is a major oversight, as mistakes in anonymization could account for the data being reversible. On the other hand, even knowing that your data could be de-anonymized by anyone with the skill set and money is alarming.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to many researchers, <strong>most data anonymization methods don\u2019t meet the requirements of current legislation<\/strong> like the General Data Protection Regulations (GDPR) or the California Consumer Privacy Act (CCPA). Here\u2019s a perfect example of how oversight on the part of companies while performing data anonymization, can lead to data exposure:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<div style=\"background-color: #b6d7a8; padding: 10px; border-radius: 25px;\">\n  <p>Researcher <a href=\"https:\/\/onezero.medium.com\/why-anonymized-data-isn-t-so-anonymous-535d2db75a2d\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">Latanya Sweeney<\/a> <strong>legally acquired anonymized medical records<\/strong> that included patient appointments, hospitalization incidents, procedures, charges, and payment methods, and <strong>then used newspaper archives to de-anonymize the data.<\/strong> \n\nShe wasn\u2019t able to obtain the names and addresses of the patients using the medical records, but the zip code was readily available. Using the unique zip code, she cross-referenced accidents reported in area newspapers against patient files. <strong>Sweeney directly connected a staggering 43% of the articles to patient files.<\/strong> \n\nBecause newspapers generally include the first and last name of the injured party, she could perform an address lookup. Essentially, <strong>all patient data for 35 individuals was de-anonymized.<\/strong>\n\n <\/p><\/div> <br><br>\n\n\n\n<p class=\"wp-block-paragraph\">This begs the question, are there any <em>truly<\/em> effective data anonymization methods?<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"which-data\"><strong>Which Data Anonymization Methods Are Most Effective?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For large corporations, the most effective methods of data anonymization are differential privacy, homomorphic encryption, and synthetic data. These methods are considered to be the most secure way to anonymize sensitive information because they present the least likely chance of de-anonymization. Here are a few examples of companies that use each of these methods:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Differential privacy<\/strong>: Apple, Google, &amp; Uber<\/li><li><strong>Homomorphic encryption<\/strong>: Microsoft &amp; Intel<\/li><li><strong>Synthetic data<\/strong>: Pharmaceuticals, Hospitals, &amp; Laboratories\u00a0<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The simplest and <strong>most effective way for individuals to increase their online anonymity is to use a VPN with extremely tough encryption<\/strong>. That way, at least you\u2019ll know you did what you could to secure your sensitive online data while in transit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to AES encryption,<strong> <\/strong><a href=\"https:\/\/www.privateinternetaccess.com\/buy-vpn-online?conversionpoint=data_anonymization\"><strong>PIA gives you access to OpenVPN and WireGuard\u00ae protocols<\/strong><\/a><strong> <\/strong>and includes a Kill Switch.

The 2021 United Nations Conference on Trade and Development announced<strong> <\/strong>that <strong>137 of 194 countries have already adopted some form of data and privacy legislation.<\/strong> That means there\u2019s still a way to go before all countries have data protection laws.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>EU countries like Sweden, France, and Ireland have some of the most all-encompassing and strict laws regarding data privacy.<\/strong> Other countries, including Egypt and Brazil, follow closely in legislation regarding personal data protection.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Not all countries offer equal, or even adequate, data privacy protections. Surprisingly, despite being home to Silicon Valley, <strong>the US falls short when it comes to creating comprehensive, nationwide data privacy laws.<\/strong><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter is-resized\"><img decoding=\"async\" src=\"https:\/\/lh4.googleusercontent.com\/x9G8LvLze5aPIovkSe9_LOEtjGC03OS2Tq3avYQb2c5B0CKMwr8zt4IWdu2nlM2QGXVDwuGlYVKyyRUV6NqP0Xz8dAwQ6G-zD-3nH4-WAJDV9Gx5YgeicwuMcJuS7aL2w8I3HVUJEp7Gjgoe8dwlvf2hKEQvs6kYv0l0gE5OqSR0J0vSZfRTe2e7Jg\" alt=\"\" width=\"500\"><figcaption>The EU contains many of the countries with strict privacy laws.<\/figcaption><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"why-best\"><strong>Data Anonymization Solutions for Everyone<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Companies wishing to implement one of these methods to anonymize customer or employee data must first determine exactly what information they want to protect.
