Description
Technical field
The present invention relates to the electronic equipment data security, specially refer to a kind of method and device of electronic apparatus system security update.
Background technology
Follow the fast development of integrated circuit, software engineering; With TV, mobile phone is the also all quick entering intelligence epoch of consumption electronic product of representative; Smart mobile phone replaces conventional mobile phone becomes the market mainstream, and intelligent television, Web TV also replace the classic flat-plate TV becomes the home media recreation center.Above-mentioned intelligent electronic device the more important thing is to have rich functions software except calculated performance is improved significantly, can live to people, work, learn to bring great convenience.
Software in the intelligent electronic device is made up of three parts usually: start-up code file, intelligent operating system file, application software and data file.Above-mentioned file still can be preserved on the storer of information after all being stored in flash memory (FLASH), ROM (read-only memory) outages such as (ROM) usually.Actuating section (Bootloader) is responsible for starting outfit, carries out simple equipment state detection, is loaded smart machine operating system.Operating system is then taken over the administrative power of entire equipment after actuating section, various resources such as dispatch processor (CPU), internal memory, storer, and according to demand management, the various application software of load operating.The various resources that application software then uses operating system to distribute are specifically accomplished various careful services, such as playing movie and video programs and so on.
The start-up code function is the simplest on the smart machine, and the position on storer is more fixing, generally is 0 to begin to deposit (relevant with concrete processor) from the address.In start-up code, then can specify the information such as deposit position, storage length of intelligent operating system.The start-up code most important function is exactly that the code of intelligent operating system is begun to read internal memory (RAM) from the storage address of appointment, jumps to then and continues in the operating system code to carry out.The position is comparatively flexible on the operating system code flash memories, can in start-up code, set.Application software code and data are then more flexible, can use the parameter in the operating system to set.
Operating system is the core place of intelligent electronic device, and is very important.But the technology of intelligent operating system own is still fast-developing, is example with Android, almost annual all once more than big edition upgrading, small-scale upgrading then has tens times more than.The upgrading of operating system is very important for the improvement of the various services of equipment, function, and therefore, intelligent electronic device such as smart mobile phone, intelligent television are upgraded through regular meeting.The upgrading of equipment brush machine generally all is to cover the old code on the flash memories (FLASH) with new software code, and it mainly is exactly operating system code in the flash memories and an application software code (brush machine, brush firmware) in the refreshing a device.If but the upgrading of brush machine is more frequent, and basically all be after equipment is sold, independently to be carried out by the consumer, owing to lack relevant device and experience, practical risk is very big.Careless slightly, the code of storing in the equipment is made mistakes, and equipment conveniently becomes " the useless machine " that can not normally start, move, and need return factory or tear the machine maintenance open.
Summary of the invention
Fundamental purpose of the present invention is the method that a kind of electronic apparatus system security update is provided, and promotes the stability of electronic apparatus system.
The present invention proposes a kind of method of electronic apparatus system security update, comprises step:
When the data of electronic apparatus system are upgraded, select master data to upgrade, and revise the judgement identification field of representative data correctness according to new situation more; Said data comprise master data and Backup Data;
