Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.

Embodiment

As shown in Figure 1, the utility model provides a kind of electronic recording handheld terminal managed for individual private information, and each terminal has unique sequence numbers, and its core is a kind of MCU chip with safety encipher function, the encrypting modules such as MCU chip has DES, AES and USB communication module.This terminal forms primarily of being with the MCU of encryption safe function, storage chip, supply module and communication module.Storage chip is connected with MCU respectively with communication module.Supply module provides stable voltage to whole terminal; Storage chip is for storing individual private information; MCU is used for encrypting and decrypting individual private information, user cipher inputting interface is also provided simultaneously and check, revise, the operation such as deletion.All the elements that MCU is saved in storage chip are all first encrypted, and during reading, then are decrypted output by MCU.MCU with encryption safe function itself has extremely strong encryption and anti-cracks function.The FLASH data storage area that individual's private information is stored in security encryption chip MCU is with in the storage chip extended out, and all information being stored in storage chip all carrys out obtaining information through the encryption of MCU chip to prevent violence from disassembling chip.The model of the MCU with encryption safe function can be adopted as Z8D256U chip, Z32 chip, Z8D168 chip, ARM-CORTEX-M0 chip or ARM-CORTEX-M3 chip.The model of storage chip can be adopted as W25Q series, and SST25VF is serial or MX25 is serial.

Concrete, the utility model provides three kinds of specific embodiments, and often kind of embodiment is all by a kind of physical interface form and user interactions, and just input display mode is different with communication modes for often kind of embodiment.

The first is U shield type, and as shown in Figure 2 and Figure 3, a similar USB flash disk, accesses individual private information in the FLASH data field of MCU and storage chip by inserting computer.It is specifically by being with the MCU of encryption safe function, USB power source processing module, storage chip and USB communication module to form.MCU with encryption safe function is connected with serial storage chip by SPI interface or I2C interface, or is connected with NAND FLASH storage chip by data bus.USB power source processing module is then to stable 3.3V the 5V voltage step-down of USB.

The second is that independent display is imported, as Fig. 4, Fig. 5, shown in Fig. 6, it increases LCD display module on U shield type basis, Keysheet module and battery module, user can separating computer direct control completely, as checked, increase, amendment and deletion account information etc., this terminal can operate on computers again after inserting USB as the terminal of U shield type simultaneously, so both can ensure that the situation lower device damaged at screen and Keysheet module still normally worked on computers by USB, allow again inputs a large amount of on computers once under normal circumstances, greatly improve the efficiency of personal information typing.Which has safety and the ease of use of highest level.It is specifically by being with the MCU of encryption safe function, USB power source processing module, storage chip, USB communication module, battery, battery supply processing module, LCD display module and Keysheet module to form.Battery by battery supply processing module for whole device provides stable supply voltage.MCU with encryption safe function is connected with Keysheet module by I/O port array.MCU is connected with display module by SPI interface or GPIO mouth.Keysheet module is used for input, checks, revises and delete individual private information, need to comprise ten key, up and down directionkeys, delete key, line feed key, switch key (input pattern switching), shift, OK button and ESC Escape.An evident characteristic of the electronic recording handheld terminal managed for individual private information is that access times are few, but require the product life cycle very long (may decades be reached), therefore power supply is applicable to adopting common removable No. 7 or No. 5 dry cells, and battery supply process is exactly that the boost in voltage of 1 joint or 2 joint dry cells is stabilized to 3.3V output.

The third is wireless connections types, as shown in Figure 7, its MCU primarily of band encryption safe function, storage chip, battery, battery supply processing module, bluetooth communication module or NFC short distance communication module composition, MCU with encryption safe function is connected with bluetooth communication module or NFC communication module by GPIO mouth, it does not have display module and Keysheet module, can visit this device by the APP software that mobile phone is special.Supply module comprises battery and battery supply processing module, battery by battery supply processing module for whole device provides stable 3.3V voltage to export.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; it should be pointed out that all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
