How does QD address security?
The QD database can be encrypted using AES-256 encryption technology. If you choose not to encrypt the database, the data is still compressed using various compression algorithms and stored in libraries on the PC. Those algorithms are different depending on the kind of data that is being compressed. A license key is required to decompress the libraries. That compression serves to obfuscate the data, without truly encrypting it. In order to access the data through the standard QD client processes, a registered user-id and password must be provided upon the first query. Passwords are stored in the QD database using AES-256 encryption with a 16-bit key. The database can be set to expire at a predetermined time and date. The expiration time and date are set when the data is loaded onto the PC. When the expiration time arrives, the computer will either erase the data completely or simply lock out all attempts to access it, depending on configuration settings. Also, the data can be automatic
