A Safe Representation Method for Matrix Text Data Storage

technical field

The invention is a safe information processing method for storing and expressing text data by using a multi-channel matrix, and belongs to the field of computer information processing.

Background technique

The current method for storing and expressing computer text data is to use a specific character set, encode it into a certain binary byte sequence, and then store it in a computer text file. The present invention is different from the current prior art text data storage and expression method. , is to first generate a matrix of {X,Y} size with N channels, where X is the number of rows, Y is the number of columns, N is the number of channels, the matrix shape is {X,Y,N}, binary bytes The data capacity is X*Y*N.

Moreover, when N is 3, the text data can also be expressed as RGB images. Such a storage and expression method is significantly different from the existing technology. .

SUMMARY OF THE INVENTION

According to the following steps, express the text data as a matrix and store it as a file, S1: encode the text data into a binary byte sequence using a specific character set, and calculate the length of the binary byte sequence as L; S2: generate a {X, Y}-sized, N-channel matrix, the matrix requires X*Y*N≥L; S3: Set the rules for storing data to a specific position of the matrix, that is, the position p of the binary byte sequence corresponds to a specific position of the matrix (x, y); S4: Set the rules for storing data to a specific channel in a specific position in the matrix, that is, the binary sequence position p corresponds to a certain channel rule in a specific position (x, y) of the matrix, because the matrix has N channel, so each (x, y) position can store N binary byte data, so different rules can be set on these N channels; S5: According to the rules of S3 and S4, store the binary byte sequence to Inside the matrix; S6: Set the rules for storing matrix data as disk files, which must be able to clearly express the number of rows, columns, channels, and the correspondence between the matrix and the secondary sequence of disk files; S7: According to S6 Rules store data to disk files.

As an improvement of [0003], S2 of [0003] can be generated as a matrix of N channels of size {X,Y}, which requires X*Y*N≥(L+3), where L is The length of the binary byte sequence of the original data, these three extra positions in the matrix, two of them are used to store the character set type used in the encoding of the original data, and the other one is used to mark whether the character set is stored in the matrix. ; As a further extension and improvement, S2 of [0003] can generate a matrix of {X,Y} size and N channels, which requires X*Y*N≥(L+z), where L is the original data binary word The length of the section sequence, there are z positions in the matrix for various markings.

According to the following steps, restore the [0003] matrix file data, S1: read the file stored in [0003] S7 as a binary byte sequence; S2: According to the file storage rules of [0003] S6, reverse restore to {X , Y}-sized matrix with N channels; S3: According to the rules of [0003] S4 and S3, read binary byte data from the matrix and restore it to the original binary byte sequence; S4: According to the rules of [0004] Read the stored character set type and other marks. If the character set or other marks are not stored, use the default value to process in the next step S5; S5: If the character set type is read out by S4, the binary value of S3 The sequence is decoded into text data according to the character set. If S4 does not read the character set type, the binary sequence of S3 is decoded into text data according to the default character set. If other marks are also read in S4, according to the mark. rules are processed.

The data can be encrypted by one or more of the following methods. The following steps are not in strict order. If the S3 rules of S1:[0003] are different, the results of the storage will be different. When this rule is used, the data cannot be restored; if the S4 rule of S2: [0003] is different, the stored result will be different. You can set a certain algorithm to jump and store it on a specific channel of the matrix, and not store it in the order of the index number, so you don’t understand the rule. If the rules of S6 are different in S3: [0003], the results of storage will be different. You can set specific rules and store them in a file format that the public does not understand. The file format here refers to the file content format, not only refers to file extension, data cannot be restored without knowing this rule.

In particular, a 3-channel text data color visualization storage method is introduced: set the channel N of S2 of [0003] to 3; set the rule of S6 of [0003] to the image format, other refer to [0003], [0004], [ 0005], [0006] store and read the data, so that the text data can be expressed in a safe color image format.

In particular, a grayscale visual storage method of 1-channel text data is introduced: set the channel N of S2 of [0003] to 1; set the rule of S6 of [0003] to the image format, other refer to [0003], [0004], [0005], [0006] Data are stored and read so that textual data can be expressed in a secure grayscale image format.

Non-text data can also be stored and restored according to the rules of the present invention. When storing, the original non-text source data can be converted into a binary sequence in [0003] S1, and other steps remain unchanged; when restoring, in [0005] Step S5 Instead of restoring binary data to text data, restore it to original non-text data.
