Problems solved by technology

This method cannot flexibly change the smart POS startup screen according to the needs of customers. The firmware needs to be updated every time the modification is made. The method of repeatedly updating the firmware is not only cumbersome to operate, but also has the risk of being maliciously replaced by the startup screen.

Embodiment 1

[0043] Embodiments of the present invention provides a method for implementing a smart replacement of a POS device boot screen, such as figure 1 As shown, including:

[0044] Step S1: When the smart POS device detects the power, check if there are screen update completion flag is executed is step S3, the otherwise step S2;

[0045] Step S2: intelligent POS device reads the default screen image file partition boot screen and as a parameter, calls the display driver to display the default startup screen, step S4;

[0046] Alternatively, the present embodiment may be a start-up screen image, video or animation;

[0047] Step S3: reads the image file smart POS device and the backup area as a parameter, calls the display driver to display the corresponding boot screen, Step S4;

[0048] Alternatively, in the present embodiment, the image file format can be implemented with different, corresponding to step S3 implemented in many ways, in the present embodiment, a detailed description of...

Embodiment 2

[0077] Embodiment 2 of the present invention provides a method of replacing the power-on POS device boot screen, in this embodiment, the smart POS device is received by the power-on picture, such as figure 2 As shown, the method of this embodiment includes:

[0078] Step 201: When the smart POS device detects the boot, check if there is an update screen to complete the flag, then perform step 208, otherwise step 202 is performed;

[0079] Step 202: The smart POS device determines whether or not the data start writing mark is presented, and then step 204 is performed, otherwise step 203 is performed;

[0080] Step 203: Smart POS devices read the screen image file in the default boot screen partition and use it as a parameter, call the display driver to display the default boot screen, perform step 209;

[0081] Step 204: The smart POS device requests to write a backup area and determines whether the backup area has write authority, and then performs step 205, otherwise step 203 is ...

Embodiment 3

[0166] POS device replacement provides an intelligent startup screen implementation method according to a third embodiment of the present invention, in this embodiment, the smart POS device receives the pixel data, such as Figure 5 As shown, the method of this embodiment includes:

[0167] Step 301: When the smart POS device detects the power, check if there are screen update completion flag is a step 308 is performed, otherwise step 302 is performed;

[0168] Step 302: smart POS device determines whether the data is written starting flag is present, a step 304 is performed, otherwise step 303 is performed;

[0169] Step 303: smart POS device reads the default screen image file partition boot screen and as a parameter, calls the display driver to display the default startup screen, step 309 is performed;

[0170] Step 304: Smart POS device application written to the backup area, and determines whether the backup area have write permission is execute step 305, otherwise, executing ...

Abstract

The invention discloses a method and device for replacing the boot screen of a smart POS device. The method includes: when the smart POS device detects that the boot screen is turned on, check whether there is an update screen completion sign, and if so, display the corresponding image according to the image file in the backup area. Boot screen, otherwise the default boot screen will be displayed according to the screen image file in the default boot screen partition; use the protection key to decrypt the ciphertext of the received image data, and verify the decrypted data. The successfully obtained data generates the image file of the boot screen and saves it; apply for writing to the backup area, if the backup area has write permission, clear the update screen completion flag, and begin to write the saved image file into the backup area; when the image file After it is completely written into the backup area, the update screen completion flag is set. The invention can replace the start-up screen alone without updating the firmware, and the operation is safe, convenient and fast, and can improve the competitiveness of products.

Description

Technical field [0001] The present invention relates to information security, and in particular relates to a method and apparatus for implementing a smart POS device startup screen replacement. Background technique [0002] In the prior art, the boot screen Android smart POS equipment in the factory burned by the POS manufacturer firmware decided, due to the Andrews smart POS equipment without the backup area, if a customer needs to replace the boot screen (branding), you need the firmware updated together. This way can not be flexible to change according to customer demand for intelligent POS boot screen, each modification required to update the firmware, repeat the firmware update not only the way the operation is complicated, and there is the risk of being maliciously replaced the boot screen. It is urgent to provide a safe and convenient method to achieve replacement of the boot screen. Inventive content [0003] Object of the present invention is to overcome the deficiencie...
