Safe proctoring tool

Mereos is a tool created for accessibility. Using our tool enables you to take exams remotely while helping to prevent fraud. Therefore it will add an incalculable value to your online assessments and certifications. Listed below are three important points to keep in mind when using Mereos on your online tests:

  1. No, you won’t be scrutinized by humans while taking your exam. Our artificial intelligence is capable of detecting any irregularity and assessing if the test is fraudulent or not. In some cases, your institution can monitor your session if the risk of fraud is high or appoint us to do so. But rest assured: your video will not be examined in the majority of cases and if it is, it would only be due to a high risk of cheating.

  2. Your information is entirely safe. Our API uses an HTTPS protocol and its communication is encrypted using Transport Layer Security (TLS). Transmission to the data center is done using TLS 1.2 or 1.3 only. Data at rest in the data center is encrypted using AES-256 and is FIPS 140-2 compliant. All data centers are SOC 3 certified and encryption is secured using AES-GCM. Our extension works exclusively within the browser and therefore has no access to your local device.

  3. We will never sell personal information. Our privacy settings are meant to protect your data and we could not access it if we wanted to. There is nothing for us to sell to third parties.

Also note that your Chrome browser may require the following permissions:

Permission 1 – “READ AND CHANGE ALL YOUR DATA ON THE WEBSITES YOU VISIT” – Unlike what it states, it does not mean our extension will read or change anything on the websites you visit. This is the permission needed by the Chrome tab capture API to allow the recording of your tabs. Tab recording will be set if, and only if, your institution decides to enable this feature on the exam you take. It is actually an optional feature. This permission is also triggered by the <all_urls> declaration which allows the extension to detect the exam. Meaning that if we did not ask for this permission, each school would need a different extension or Mereos would be forced to release permission updates every time a new customer wanted to use our Mereos extension, which would be far too complex and time-consuming.

Permission 2 – “CAPTURE THE CONTENT OF YOUR SCREEN” – This allows us to provide technical support if you need it. This is also an optional feature that your exam administrator decides to set or not. Google Chrome will ask you twice about this permission and will also place a message at the bottom of your screen to remind you at all times that your screen is being captured. Screen capture will automatically end once you finish your exam.
