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] Embodiment 1 of the present invention provides an implementation method for replacing the boot screen of a smart POS device, such as figure 1 shown, including:

[0044] Step S1: When the smart POS device detects that it is powered on, check whether there is an update screen completion flag, if yes, execute step S3, otherwise execute step S2;

[0045] Step S2: The smart POS device reads the screen image file in the default boot screen partition and uses it as a parameter, calls the display driver to display the default boot screen, and executes step S4;

[0046] Optionally, the boot screen in this embodiment can be a picture, video or animation;

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

[0048] Optionally, in this embodiment, the image file format can be implemented in different ways, and the corresponding step S3 ha...

Embodiment 2

[0077] Embodiment 2 of the present invention provides an implementation method for replacing the startup screen of the smart POS device. In this embodiment, the smart POS device receives the startup screen, such as figure 2 As shown, the method of the present embodiment includes:

[0078] Step 201: When the smart POS device detects that it is turned on, check whether there is an update screen completion flag, if yes, execute step 208, otherwise execute step 202;

[0079] Step 202: The smart POS device judges whether there is a data start writing mark, if yes, execute step 204, otherwise execute step 203;

[0080] Step 203: The smart POS device reads the image image file in the default boot screen partition and uses it as a parameter, calls the display driver to display the default boot screen, and executes step 209;

[0081] Step 204: The smart POS device applies for writing to the backup area, and judges whether the backup area has write permission, if yes, execute step 205...

Embodiment 3

[0166] Embodiment 3 of the present invention provides a method for implementing a smart POS device to replace the boot screen. In this embodiment, the smart POS device receives pixel data, such as Figure 5 As shown, the method of the present embodiment includes:

[0167] Step 301: When the smart POS device detects that it is turned on, check whether there is an update screen completion flag, if yes, execute step 308, otherwise execute step 302;

[0168] Step 302: The smart POS device judges whether there is a data start writing mark, if yes, execute step 304, otherwise execute step 303;

[0169] Step 303: The smart POS device reads the image image file in the default boot screen partition and uses it as a parameter, calls the display driver to display the default boot screen, and executes step 309;

[0170] Step 304: The smart POS device applies for writing into the backup area, and judges whether the backup area has write permission, if yes, execute step 305, otherwise exec...

Abstract

The invention discloses an implementation method and device for replacing a startup picture of intelligent POS equipment. The method comprises the steps of checking whether a picture updating completion mark exists or not when the intelligent POS equipment detects the startup, if yes, displaying a corresponding startup picture according to a mirror image file in a backup region, or otherwise, displaying the default startup picture according to the picture mirror image file in the default startup picture partition, decrypting the received image data ciphertext by using the protection key, verifying the decrypted data, and if the verification succeeds, generating a mirror image file of the startup picture according to the successfully decrypted data and storing the mirror image file, applying to write in a backup region, if the backup region has the write-in permission, clearing the picture updating completion mark, and starting to write the stored mirror image file into the backup region, and when the mirror image file is completely written into the backup region, setting a picture updating completion mark. The startup picture can be independently replaced without updating firmware, the operation is safe, convenient and fast, and the product competitiveness can be improved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for replacing the startup screen of an intelligent POS device. Background technique [0002] In the prior art, the boot screen of the Android smart POS device is determined by the firmware burned by the POS manufacturer before leaving the factory. Since the Android smart POS device has no backup area, if the customer needs to change the boot screen (brand promotion), it needs to be updated with the firmware. update together. This method cannot flexibly change the smart POS boot screen according to the needs of customers. Every modification needs to update the firmware. The method of repeatedly updating the firmware is not only cumbersome to operate, but also has the risk of maliciously replacing the boot screen. Therefore, it is urgent to provide a safe and convenient method for replacing the boot screen. Contents of the invention [0003] The purpose o...
