This products is a personal safe database that can store your online password, credit card details, contact details and confidential notes. The user interface is intuitive and latest software technologies have been used to ensure customer satisfaction. The user will have 2 Levels of security. 1st Level of security comes with the Time Lock feature that locks the program if left unattented with configurable idle timer between 0 and 10 minutes. The Time Lock is also visually fabilous with an animated safe button that emulates opening once Time Lock password has been used to unlock. 2nd Level of security comes with the encryption feature that allows you to encrypt and decrypt your Verilune Personal Safe (.vps) with 5 different algortihms and strong keywords upon file save and file load. Technologies used in this product are benefits of using .NET 3.5 sp1 to its fullest potential both visually on the font end and virtually in the backend databinding and serialization of data. Why Personal Safe? One tool to safely store all your private information. Until now the alternative has been to install different application for different types of information.
Safe�n�Sec is complex data and user applications protection against threats and vulnerabilities for individual PC as well as workstations in corporate networks.
The program uses proactive technology based on activity analysis in user PC. That means any applications activity, operation system services, user actions, external activity analysis etc. Unlike out-of-date technologies used in antiviruses and personal firewalls which analyze program code proactive technologies ANALYZE BEHAVIOR of applications for its potential maliciousness).
Being installed Safe�n�Sec provides:
Protection against viruses, hacker attacks and spyware modules with help of any activity control on the PC and blocking all malicious actions.
Protection against breaking in and unauthorized access by means of exploit-attacks, system register and OS services status changes detection and user data excess limitation (documents, address books, registry data etc.)
Topaz Moment!(TM) is a software that allows you to capture high quality and mega-pixel pictures from video.
Topaz Moment! (TM) uses the most advanced super-resolution technologies to enhance pictures. Our proprietary technologies analyze multiple frames of video and use information in all the frames to obtain an enhanced picture. This produces images of much higher quality and resolution than is possible using a single frame.
The enhanced pictures can then be saved in a variety of image file formats, or send directly to another program.
