Abstract

The invention discloses a display for protecting data. The display comprises a display screen, a display card, a secure flash memory device and a detector. The detector detects whether the display isin a safe environment or not, if the display is in the safe environment, the safe flash memory device is controlled to process the data needing to be sent to the display card to be displayed, and theprocessed result is sent to the display card to be displayed. If the terminal is in the unsafe environment, the data needing to be sent to the display card to be displayed is not processed, but the data is directly sent to the display card, so that the displayed data is effectively protected.

Description

[0001] (1) Technical field [0002] The present invention relates to displays, in particular to displays with protected data. [0003] (2) Background technology [0004] Information security has drawn more and more attention from people. Commonly used technical means are to prevent illegal users from accessing protected information by adding biometric information authentication methods such as digital passwords, fingerprints, and faces. Another commonly used technical method is to build a trusted computing environment for computer systems. The main method is to call the internal algorithm of TCM (Trusted Cryptography Module, Trusted Cryptography Module) to carry out level-by-level trustworthiness for each component in the computer system startup process. Metrics to determine whether a computer system has been attacked or compromised. It can be seen that trusted computing ensures information security by confirming the security of each component in the system. [0005] The abov...
