Abstract: An anti-operation system in an electronic apparatus includes a detecting module, an identifying module, and a controlling module. The detecting module detects whether there is a touch-controlled program being activated and controls a pattern detection device to detect the detailed pattern of the object touching on the touch device. The identifying module verifies the pattern detected by the pattern detection device by reference to at least one predetermined fingerprint pattern. The controlling module determines whether an instruction apparently given should be acted upon or ignored according to a result of the verification made by the identifying module.

Abstract: An electronic device for managing file authorization is provided. The electronic device stores encrypted files. Each encrypted file presets a predetermined password. When receiving an operation signal of one of the encrypted file, the electronic device determines whether the operation signal matches the predetermined password of the selected file. The electronic device processes the file in response to the operation signal if the input matches the predetermined password of the selected file, and does not respond to the operation of the selected file if the input does not match the predetermined password of the selected file.

Abstract: A portable electronic device includes a plurality of touch sensing units for covering a surface of the portable electronic device. Each touch sensing unit is capable of generating touch sensing signals when the touch sensing units are touched. The portable electronic device stores at least one predetermined figure. The portable electronic device determines positions of the touched touch sensing units on the surface of the portable electronic device when the touch sensing unit is touched, and generates a touch figure according to the determined position of each touched touch sensing unit on the surface of the portable electronic device. The portable electronic device computes a similarity degree between the generated touch figure and the predetermined figure, and generates an alarm instruction to control an alarm unit to output an alarm signal if the computed similarity degree is greater than the predetermined value.
