  • Patent number: 11647053
    Abstract: A compliance check system to provide compliance validation for a user system is described. The compliance check system includes a compliance checker plug-in on a device used to access a secured resource. The compliance checker plug-in receives a request for compliance validation prior to providing access to a secured resource, and triggers one or more compliance checkers. In one embodiment, the compliance checker is a device encryption compliance checker configured to determine whether a device drive is encrypted. In one embodiment, the compliance checker is a password compliance checker configured to determine whether passwords in the user system comply with password compliance requirements. The compliance checker plug-in further to verify the compliance status of the device, based on data from the compliance checkers.

  • Patent number: 11050790
    Abstract: A compliance checker to verify that a device complies with a policy is described. In one embodiment, the compliance checker comprises a compliance checker agent, to initiate the compliance check, in response to receiving the request, and an encryption checker to obtain an original data and a data stored on the storage. The system further comprising a comparator to determine whether known data read from the upper driver is identical to known data read from the lower driver. The compliance checker plug-in in one embodiment verifies the compliance status of the device, based on the data from the comparator.

  • Patent number: 10860723
    Abstract: A compliance checker to verify that a device complies with a policy is described. In one embodiment, the compliance checker comprises a compliance checker agent, to initiate the compliance check, in response to receiving the request, and an encryption checker upper driver above a level of a disk encryption driver, and an encryption checker lower driver, below the level of the disk encryption driver with a comparator to determine whether known data read from the upper driver is identical to known data read from the lower driver. The compliance checker plug-in in one embodiment verifies the compliance status of the device, based on the data from the comparator.

  • Patent number: 8667273
    Abstract: A method and apparatus for secure transparent backup and encryption of data including compression, elimination of redundant information, all working integrated whether data is stored locally or shared in networks. When data is shared in networks, several computers may access encrypted objects simultaneously with the same limitations as for non-encrypted objects. The method and apparatus can automatically and invisible take backups and can easily restore any object to the exact content as it existed for a selected point in time using a snapshot capability in combination with the user interface described that has its focus on making the use very easy for the end user. The invention offers security and performance enhancements when used with tables containing approved hashes for executables and other objects based on company policy and virus scanning. Specific objects may also be easily detected even if they are encrypted.
