Hand-held electronic device and its used method for processing graphic data

Abstract

The electronic device includes storage unit, system menu hidden unit, image files hidden unit and display unit. the said storage unit includes image file repository for storing image files, and security data repository for storing security data of system and security data of image file. The system menu hidden unit in use for setting up the said security data of system compares whether the first input character string is accorded with the said security data of system; if yes, the unit sends a command for displaying system menu to let the display unit to show system menu of the image file repository. The image files hidden unit in use for setting up the said security data of image file compares whether the second input character string is accorded with the said security data of image file; if yes, the unit sends a command for displaying image files to let the display unit show the same.

Description

technical field [0001] The present invention relates to a device and method for processing graphic files, in particular to a device and method for hiding and displaying graphic files suitable for handheld electronic devices. Background technique [0002] The functions of handheld electronic devices (such as mobile phones, personal digital assistants, etc.) are increasingly complex, and models with Internet access, multimedia short message functions and digital camera functions are gradually becoming popular, making images processed and stored by handheld electronic devices The number of files is increasing, and the size and fineness of the image files are also getting higher and higher. However, known devices such as mobile phones and personal digital assistants do not provide functions such as encryption or hiding of stored image files, and cannot provide protection for image files in the system. In this way, users cannot control Whether the image files stored in this type...

Problems solved by technology

However, known devices such as mobile phones and personal digital assistants do not provide functions such as encryption or hiding of stored image files, and cannot provide protection for image files in the system. In this way, users cannot control Whether the image files stored in this type of handheld electronic device should be shared with others. When the mobile phone or personal digital assistant is lost or used by a third party other than the user, the image files stored in it will be shared by others. Watching or using, the personal privacy of the owner of the picture file may be violated

[0003] In short, the known handheld electronic devices cannot provide security functions such as encryption or hiding for the image files stored therein, which causes doubts about the user's personal privacy and data security.
