The bar code coding method provided by the embodiment of the invention is applied to electronic equipment capable of realizing information encryption and coding, wherein the electronic equipment can be a two-dimensional code encoder comprising a symmetric encryptor and also can be intelligent terminal equipment capable of realizing information encryption and coding.
In order to reduce the number of bar codes and improve the security of information in the bar codes, in the embodiment of the invention, the electronic device can encrypt the information in the bar codes to generate a two-dimensional code, and in order to encrypt the information in the bar codes, the electronic device firstly acquires each piece of information carried in the bar codes.
In the embodiment of the invention, the bar code is a bar code to be processed, namely the bar code which is encrypted in the bar code, the number of the bar codes to be processed is at least two, and the bar code to be processed comprises a one-dimensional bar code and a two-dimensional bar code.
The electronic device obtains each piece of information carried by the barcode to be processed, and specifically, the electronic device scans the barcode to be processed, decodes the barcode, and obtains each piece of information carried by the barcode. Because the same information may exist in each piece of information carried in the bar code, the electronic device can also remove redundant information repeated in the information after acquiring each piece of information.
S102: and determining a first number of target bar codes carrying the information according to the acquired information, and determining a target encryption level of the information according to the first number and a second number of the bar codes to be processed.
In order to encrypt information, in the embodiment of the invention, because the information is disclosed to different degrees, the encryption level required by the information is different. In the embodiment of the invention, if the number of times of a certain piece of information appearing in a bar code is more, the higher the disclosure degree of the piece of information is, the lower the encryption level required by the piece of information is; if the number of times of the bar information appearing in the bar code is lower, the lower the disclosure degree of the bar information is, and the higher the encryption level required by the bar information is.
In order to determine the specific encryption level of each piece of information, the electronic device may further determine, for each piece of acquired information, a first number of target barcodes carrying the piece of information, and specifically, after the electronic device acquires each piece of information carried by each barcode, may determine, for each piece of information, a target barcode carrying the piece of information, so as to determine the first number of target barcodes.
After the electronic equipment determines the first number of the target bar codes carrying the bar information, in order to determine the specific encryption level of the bar information based on the disclosure degree of the bar information, the electronic equipment also stores the second number of the bar codes to be processed in advance, and according to the first number and the second number, the electronic equipment determines the target encryption level of the bar information.
S103: and encrypting each piece of corresponding information by adopting the target encryption key according to the target encryption level of each piece of information and the corresponding relation between the pre-stored encryption level and the encryption key to generate the target two-dimensional code.
In order to encrypt information, the electronic device prestores a corresponding relation between an encryption level and an encryption key, and according to a target encryption level of each piece of information, the electronic device determines a target encryption key corresponding to the target encryption level in the corresponding relation.
And according to the target encryption key, the electronic equipment encrypts each piece of corresponding information by adopting the target encryption key. Specifically, the electronic device encrypts the target encryption key based on the existing encryption algorithm to obtain encrypted information. The encryption algorithm for encrypting each piece of information may be the same or different, preferably, the encryption algorithm for encrypting each piece of information is the same, and the electronic device may employ a symmetric encryption method for encrypting each piece of information. Encrypting information in a symmetric encryption manner is the prior art, and the embodiment of the present invention is not described herein in detail.
According to the embodiment of the invention, the information in all the bar codes is acquired, the number of the bar codes carrying the information is determined for each piece of information, the information is encrypted based on the number of the bar codes carrying the information, the encrypted information is concentrated in one target two-dimensional code, and the encryption key is determined based on the encryption level of the information when the information is encrypted, so that the safety of the information is improved.
Example 2:
to determine the encryption level of the information, on the basis of the above embodiment, in an embodiment of the present invention, the determining the target encryption level of the piece of information according to the first number and the second number of barcodes to be processed includes:
and determining the target encryption level of the piece of information according to the difference value between the second quantity and the first quantity, wherein the smaller the difference value is, the lower the target encryption level is, and if the difference value is 0, the target encryption level is a non-encryption level.
In order to determine the encryption level of the information, after the electronic equipment determines a first number of target barcodes carrying the piece of information and a second number of barcodes to be processed, the electronic equipment determines a difference value between the second number and the first number, and the difference value is determined as the target encryption level of the piece of information.
If the difference is 0, the disclosure degree of the bar information is completely disclosed, that is, each bar code to be processed carries the bar information, so that the target encryption level of the bar information is a non-encryption level. If the difference value is 1, the target encryption level of the piece of information is a first encryption level; if the difference value is 2, the target encryption level of the piece of information is a second encryption level, and the second encryption level is higher than the first encryption level; if the first number of the target bar codes carrying the piece of information is 1, only one target bar code carries the piece of information, and when the difference value is the difference value between the second number and 1, the encryption level of the piece of information is the highest encryption level.
Example 3:

In order to improve the accuracy of information encryption, in the embodiment of the present invention, the information corresponding to the same encryption level is different, so that after the electronic device determines the target encryption level of the piece of information, the electronic device may further determine the identification information of the piece of information in order to distinguish the information.
Because each bar code to be processed has corresponding identification information, the electronic equipment determines a target identification information combination corresponding to each piece of information according to the identification information of each target bar code carrying the piece of information, and the target identification information combination is the identification information of the piece of information.
The identification information of the bar code can be numbers, letters or other information for uniquely identifying the bar code. For example, the identification information of the barcode is 1, 2, 3, 4, or the identification information of the barcode is the letter A, B, C, D. When the identification information of the barcode is a letter A, B, C, D, if the identification information of the target barcode carrying the bar information is A, B, C, determining that the target identification information combination corresponding to the bar information is ABC, wherein the target identification information combination does not distinguish the sequence of each piece of identification information, and the target identification information combination BCA and ABC belong to the corresponding target identification information combination, i.e., the identification information of the bar information.
After the electronic device determines the target identification information combination corresponding to the piece of information, in order to determine the target encryption key of the piece of information, the electronic device also prestores the corresponding relationship between each identification information combination and the encryption key, determines the target encryption key corresponding to the target identification information combination in the corresponding relationship, and encrypts the piece of information by using the target encryption key.
