ArtistScope Site Protection System (ASPS)

ArtistScope

ArtistScope Site Protection Software (ASPS) provides the most robust and most secure website security and copy protection for all web page media, safe from all copy including screen capture, download, scraping, etc. In fact ASPS provides the most secure solution for data security and the prevention of data loss and plagiarism ever imagined. The ASPS server module is installed on the web server (Apache or Windows) to deliver encrypted web pages from your web site that only the ArtisBrowser can interpret and display, creating a secure tunnel between website and the user's web browser in which no data or media can be copied or extracted by any means, not even from browser cache or memory. ASPS is most unique and it is most secure because it does not depend on popular web browsers which are useless for copy protection. Any media displayed on your web page will be copy protected and you can use any video file format or embedded player that you like.

NoPass

NoPass™ is a multi-factor authentication add on for remote users. In addition to the username and password, NoPass™ performs two additional factors of authentication – something you have and something you are. This utilizes smartphones and does not require the purchase of additional hardware authentication devices for each user. It also does not use SMS, which can also be costly and is vulnerable to being intercepted. With the increase in phishing and other identity attacks in our day and age, authentication that requires a username and password (like RADIUS) can be potentially at risk. Sophisticated social engineering schemes and clever tactics can fool even the savviest of users. In order to combat this, Identité™ has introduced its NoPass™ Employee MFA solution, a lightweight feature that enhances the overall security and is adaptable with the leading authentication protocols that are in the market.

Ziroh Store

It’s unsafe to store/sync your critical files to cloud storage platforms. Because there is no cloud that is able to keep your details completely private to you. All your files on the cloud are telling tales about you to your cloud storage provider, your personal images, academic transcripts, bank details, and work documents. You really don’t have a say in who reads your information, and what they do with it. When you sync your gallery to your cloud, it exposes the personal photos and videos on your device to all third parties who have a backdoor to your cloud storage. They are privy to every private moment you capture and even delete. Do a simple search to check when your cloud storage provider was last hacked. Your files on the cloud are private to you, your cloud storage provider and their allies only until a savvy hacker looks your way. Ziroh Store is a privacy-preserving intuitive software that helps you to upload your files end-to-end encrypted to any of your cloud platforms.
