DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a system and method of the invention, and in particular to a text encryption system and method. [Prior Art] With the advent of the digital age, information digitization has become an inevitable trend, but due to the dissemination and copyability of information (such as: text, images, images...), and the booming network It makes it easy for people to get information from the Internet. Therefore, the digital information is no longer as good as the singer. From the perspective of Sakizaki’s authority and the status of intellectual property rights, it has become a concern. Urgent problems. ^, at present, the most widely used is a _factory watermark coding technology. The so-called "watermarking technology ^ L is to embed some of the information related to the original digital information in the original digital information to be transmitted, so that An authorized third party is not allowed to use the unauthorized original number = Beixun arbitrarily, and it is obvious that the 'Dragon's watermarked digital dragon and the original number (four) are obvious, that is, hidden (four), not letting people There are some kinds of digital information in the video recording. This way, the digital information will be used in such a way as to reduce the intention of the person concerned to destroy the information. However, in the current practice, the 卩_, = bit processing i-type to obtain the digital poor news, it has - the corrective protection of the problem is confirmed by the reduction operation, that is, lost the role of copyright protection. Therefore, it is necessary to propose a kind of text encryption pure and method two. In the paper-based display process, the explicit indication can be made to prevent the illegal person from pirating by taking pictures, printing, etc. SUMMARY OF THE INVENTION A text encryption system is provided, the system includes a storage unit, and the text # is used for the wide: start position determining module, an encryption module and a saving module. And in the present, the green east 1 is used to store text information, wherein the text includes the north/denier, the middle storage, the corresponding-rough grain rough background and smooth background, the L texture feature and the slip texture feature. The f-field corresponds to the _pixel marker, where 1272814 corresponds to the luminance value. The text acquisition module is configured to extract, from the storage unit, a text box. The encrypted location determining module is configured to determine that the information saving and saving module is configured to: the encrypted text sub-module is determined to include a group of sub-blocks, the background block analysis, the block determination The dice group and a pixel point determine the sub-module. The background block is divided into a number of background blocks that do not overlap each other and are equal in size. The feature i of the block is analyzed as the n of the f block, that is, the _background area is added. Pixel H is used to base pixels in a coarser background block based on the function. To add the inr encryption method, the method includes the following steps: (1) obtaining the text back to the background including the background, including the background and the smooth background, the background is Wei 2 splitting the text 'Μ is a smooth background block' The pixel is in the middle; according to the function, the current brightness value of the pixel in the encrypted moonlight block is obtained; and (g) the file is saved in the form of 歹=, etc., thereby preventing the illegal person from Photographing, [Embodiment] Storage list: two-text ^ text = dense f, unified module architecture diagram. The system includes a 13, and - save module 14. In addition, the memory = element = mouth-tight position determination module 12, - the encryption module includes the background, talk about the past," and the error is used to store text information, wherein the text package m and the rough background and the smooth background correspond to one Rough texture features and a 7 8 1272814: slip texture feature. The foreground is reduced by the pixel point file = can be _ number two into the remaining yuan silk record. For example, when the pixel point is represented by an 8-bit binary bit, the display material is white-shoulder, the luminance value of the prime point is “〇”, and the white pixel_luminance value is “255” ”, The brightness values of the denier points are randomly distributed in the "〇,, to the "255,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, For example, it can be 8 bits, 16 bits, 32 bits, and the bit = the pixel level brightness level shown. The above indicates the pixel point luminance value binary bit = application section. The text gets the U, and the gift element cap takes the background pixel right of the plus. The encrypted position determining module 12 determines the j-rough background towel to be encrypted. Encryption is done 13 and the woven weave is encrypted in position. The health module 14 is configured to display the encrypted text storage module 1 as shown in the second figure, which is a block diagram of the encrypted location determining module in the module architecture diagram of the present invention. The encryption location grafting module, group 12 includes a back-parent segmentation sub-module 12〇, a background block analysis sub-module 121, a background block determination sub-module 122, and a pixel determination sub-module. The background block dividing sub-module 12〇 is configured to divide the text background into a plurality of background blocks of equal size and non-overlapping, that is, the background pixel points are divided into equal-sized pixel blocks, and the pixel block size can be Depending on the application, for example, it can be 8χ8, 16χ16, 32χ32 size pixel blocks. Background The block analysis sub-module m is used to read the background block and perform texture feature analysis on the background in the background block, that is, the pixel block, according to an analysis function. Wherein the analysis function is a conventional image analysis function. The background block determining sub-module (2) is configured to compare the analysis result with a predetermined value to determine a texture feature of the background block. The pixel determination sub-module 123 is configured to determine a pixel point in the encrypted background block according to a function. Wherein the function is a conventional position determining function. As shown in the third figure, it is a flowchart of the text encryption method of the present invention. First, the text acquisition module 11 obtains text information to be encrypted from the storage unit 10, wherein the text includes a background including a rough background and a smooth background, corresponding to a rough texture feature and a smooth texture feature, respectively. The background is correspondingly represented by a pixel dot file, each pixel point of the pixel dot file corresponding to a threshold value, which can be represented by a plurality of binary bit bits (step S300). The encrypted position determining module 1272814 12 determines that the pixel points in the rough background are added (steps). The training group i3 adjusts the current brightness value of the pixel in the rough background corresponding to the plus position according to an adjustment value. The adjustment can include the brightness value according to the adjustment value and the current brightness value, which can be - a certain percentage, and the brightness value of the pixel point does not exceed the brightness value. For example, when ^3 is represented by an 8-bit binary bit (that is, a black-and-white background) with a current luminance value of 12^, the adjusted luminance value is 6〇. When the pixel value is 肖)) The current brightness value of the table (ie, the color background) is (126, 126, 126). When the current brightness value is reduced by 50%, the adjusted brightness value is (63, 63, (6). ^ The position of the woven image can be corresponding to the _ binary cryptographic training element (for example, the two 位 position withdrawal can correspond to the corresponding binary plus position (10) Γ by step S302). The security group 14 will be encrypted The text δ ΐ ΐ is stored in the storage ΐ ΐ ( ( (step S303). The above process may be used as an encryption process for a page of text information, and therefore, for the positive e-book object domain lie, the above domain is implemented., 8301 ° block ( Each care m is n non-overlapping, large-scale background areas of the scale, that is, the background pixel points are divided into small equal-sized symplectic blocks, ZT^rtAM ^ 8x8 ^ 16x16 * 32-2 ^ ° ^ analysis sub-module 121 Reading a background block 1 , where 〇 < also (step merging and generating omni-group 121 analyzes the background block i texture according to an analysis function _2). The analytic function can be a conventional image Analysis function (step identification). The moon-shaped block green stator model M122 will return to the thief, return to the ruling; Point determining sub-module;;==== Two's returning one, the function may be the same as the fifth figure, which is an embodiment of real-text encryption using the present invention. In this example, the implementation of 8 1272814 The string-return % table does not encrypt the information, and the towel is encrypted by the lake to verify the version of the text. The encrypted position is woven and the value is audible - the encrypted information binary bit = (for example, υ 'minus' The image plane luminance value that is not wrapped in the domain position can be encrypted on the other side, and the binary bit (for example, G). By adjusting the brightness value, the explicit encryption is performed. Τ U acquires the 1G towel from the storage element.
