Abstract: A data protection method is provided. The data protection method includes the following. A first image is obtained; at least one first object image in the first image is identified; the at least one first object image is analyzed to capture multiple first characteristic values of multiple characteristic points of the at least one first object image; and an encryption key is generated according to the first characteristic values.

Abstract: A network level virus monitoring system capable of monitoring a flow of network traffic in any of a number of inspection modes depending upon the particular needs of a system administrator. The system includes a network virus sensor self registration module coupled to a network virus/worm sensor arranged to automatically self register the associated network virus/worm sensor. The monitoring provides an early warning of a virus attack thereby facilitating quarantine procedures directed at containing a virus outbreak. By providing such an early warning, the network virus monitor reduces the number of computers ultimately affected by the virus attack resulting in a concomitant reduction in both the cost of repair to the system and the amount of downtime. In this way, the inventive network virus monitor provides a great improvement in system uptime and reduction in system losses.

Abstract: In a distributed network having a number of server computers and associated client devices, method of isolating infected client devices from uninfected client devices is described. The method is carried out by correlating network related virus infection information, determining if a virus outbreak has occurred based on the correlated information, isolating infected client devices from uninfected client devices when the virus outbreak is confirmed, monitoring all data packets in the network for the virus, identifying a packet type associated with the virus, and blocking only the identified packet type.
