The main solutions of the embodiments of the present invention are: storing user identification information on a terminal used by a user, generating a corresponding identification watermark by the identification information of the user when the user sends the information, combining the generated identification watermark with the information sent by the user, and performing inverse Fourier transform to generate an invisible watermark, so that the user identification information is added to the information sent by the user, and meanwhile, the reading of a receiver is not influenced by the information sent by the user; when information leakage occurs, the terminal carries out Fourier transform on the information, so that user identification information is displayed to determine the source of the information leakage.
Because the prior art adds the watermark on the electronic document, a user can delete personal information through means such as PS (PS) and the like when sending the information, the method can protect secret-related data to a certain extent, and the risk of stealing the secret-related data is reduced; however, the protection mode can only embed watermarks in certain specific positions of the secret-related data at first, and cannot fully cover all secret-related contents, so that a stealer can intentionally avoid the watermarks to steal other parts of the secret-related data, the source of information leakage cannot be determined when information leakage occurs, and the information security cannot be effectively protected.

Referring to fig. 2, in a first embodiment of the information security processing method of the present invention, the information security processing method includes:
step S10, judging whether the information is in an information protection mode, and if the information is in the information protection mode, acquiring initial information associated with a sending instruction when the sending instruction is detected.
When a user starts the terminal or the user performs terminal operation, the terminal judges whether the mode in which the terminal is positioned is an information protection mode, and it is required to be noted that the terminal information protection mode can be automatically set by a server or other monitoring devices, or can be set by the terminal user independently, if the terminal is determined to be in the information protection mode, when the terminal detects that the user performs operation based on the terminal, the terminal automatically triggers an operation detection request, a terminal processor receives the operation detection request and detects an operation performed on the terminal, when the terminal processor detects that an operation corresponding instruction triggered by the user is a sending instruction, the terminal acquires initial information associated with the sending instruction, wherein the initial information can be different types of information such as image information, electronic documents or instant messages, for example, a science and technology company sets work computers of all staff as the information protection mode, when the work computer processor detects that the sending instruction of a screen capture image is triggered on instant communication software of the terminal, the terminal acquires the screen capture image associated with the sending instruction, and the terminal performs information security processing by taking the screen capture image as the initial information.
And S20, performing discrete Fourier transform on the initial information to generate information to be edited.
The terminal performs a discrete fourier transform (Fourier Transform) on the initial information. For example, the initial information is a screen capturing image, the terminal processes the screen capturing image through a preset discrete fourier transform formula, wherein the frequency and the like of the image in the preset discrete fourier transform formula can be set according to actual conditions so as to distinguish low-frequency information from high-frequency information in the image, the terminal filters a frequency domain after the discrete fourier transform to obtain information to be edited which accords with information superposition, and it is required to supplement that parameters in the discrete fourier transform in the invention are not particularly limited and can be determined according to the effect of the processed initial information.
Step S30, obtaining a preset user identifier, and encoding the user identifier to generate an identifier watermark.
The terminal obtains preset user identification in the local storage, wherein the user identification is user name, user work number or other user post information, the user identification can be input in advance by a user, the user identification information can be automatically obtained according to user operation, the user identification information is identification information which can uniquely identify the user identification and is obtained through discrete Fourier transform, and the terminal carries out coding processing on the preset user identification, wherein the coding processing is a technology for representing images by using fewer symbols (bit numbers); the image coding method mainly comprises symbol coding, predictive coding, transformation coding, sub-band coding, wavelet transformation coding, split-dimension coding and the like, and generates an identification watermark corresponding to the user identification.
And S40, superposing the information to be edited and the identification watermark, performing inverse Fourier transform, and generating transmission information corresponding to the transmission instruction.
And the terminal performs superposition processing on the information to be edited and the identification watermark and performs inverse Fourier transform, namely, the terminal performs superposition processing on the information to be edited and the identification watermark which are subjected to superposition processing, so that the tangible identification watermark is converted into an invisible identification watermark, and the terminal takes the information obtained through inverse Fourier transform as transmitting information so as to transmit the transmitting information to a corresponding user.
In step S40, the information to be edited and the identification watermark of the terminal may be superimposed in different manners;
for example, in the first mode, the size of the superimposition processing is performed according to the information to be edited and the identification watermark: the terminal obtains the size of the information to be edited and the size of the identification watermark, calculates the area of the information to be edited and the area of the identification watermark, and automatically sets the position relationship between the information to be edited and the identification watermark according to the area ratio of the information to be edited and the area ratio of the identification watermark so as to carry out superposition processing on the information to be edited and the identification watermark; for example, the size of the information to be edited is 20cmx10cm, the size of the identification watermark is 5cmx5cm, the area ratio of the information to be edited to the identification watermark obtained by the terminal is 8:1, the terminal equally divides the surface of the information to be edited into 8 parts, and the identification watermark is correspondingly placed on the information to be edited; and the second mode is that the terminal sets the information to be edited and the identification watermark to carry out superposition processing, namely, the terminal sets the identification watermark to be smaller in size, and the terminal randomly sets the identification watermark on the information to be edited to finish superposition processing of the information to be edited and the identification watermark.
In this embodiment, the terminal performs superposition processing on the information to be edited and the identification watermark, and performs inverse fourier transform to hide the identification watermark, so that the user identification is added and fused with the information to be edited on the premise of not affecting the reading of the user, and meanwhile, in this embodiment, the position of the identification watermark is set according to the size of the identification watermark, so that the identification watermark is randomly and comprehensively set on the information to be edited, and the user cannot reject the identification watermark, thereby improving the information security.
And step S50, the sending information is sent to a receiving account associated with the sending instruction, so that the receiving account corresponds to a user to check the sending information.
And the terminal sends the sending information to the receiving account associated with the sending instruction, so that the receiving account can be used for corresponding to the user to check the sending information, namely, the terminal extracts the sending account information of the user in the sending instruction and sends the sending information to the receiving account associated with the sending instruction.
In the embodiment, by storing a user identifier on a personal computer of an enterprise or a public institution and setting a computer security mode, when a user processes information, judging whether the user is in an information protection mode, if the user is in the information protection mode, acquiring initial information associated with a sending instruction when the sending instruction is detected; performing discrete Fourier transform on the initial information to generate information to be edited; meanwhile, the terminal acquires a preset user identifier in the local storage, and encodes the user identifier to generate an identifier watermark; the terminal carries out superposition processing on the information to be edited and the identification watermark, carries out inverse Fourier transform, and generates transmission information corresponding to the transmission instruction, wherein the transmission information carries the invisible watermark of the user identification; and the terminal sends the sending information to a receiving account associated with the sending instruction so that the receiving account can view the sending information corresponding to the user. When information leakage occurs, the information can be analyzed to obtain a corresponding user identifier so as to determine the information leakage source and ensure the information safety.
Further, the present embodiment of the present invention is provided on the basis of the first embodiment of the present invention, which is a refinement of step S30 in the first embodiment, and specifically illustrates a processing step of identifying a watermark.
Specifically, referring to fig. 3, in step S30 of the information security processing method, the information security processing method includes:
step S31, obtaining a preset user identifier, and encrypting the preset user identifier according to a preset rule.
The terminal acquires a preset user identifier in the local storage, and encrypts the preset user identifier according to a preset rule (the preset rule refers to a preset encryption rule, that is, the terminal or the user is an encryption rule preset according to factors such as conditions input by an information type user), wherein the asymmetric encryption is described as the preset rule, and an asymmetric encryption algorithm on the terminal needs two keys: public keys (publickeys) and private keys (privatekeys). The public key and the private key are a pair, and if the data is encrypted by the public key, the data can be decrypted by the corresponding private key; if the data is encrypted with a private key, it can only be decrypted with the corresponding public key.
In the implementation, because two different keys are used for encryption and decryption, when information leakage occurs, only the characteristic decryption rule can decrypt the leaked information, so that the watermark addition of the information to be edited is realized while the security of the user identification information is ensured.
And step S32, after the completion of the encryption of the preset user identification is detected, carrying out random encoding on the preset user identification to generate an identification watermark, so that the identification watermark and the information to be edited are subjected to superposition processing.
After the terminal detects that the encryption of the preset user identification is finished, for example, corresponding prompt information is generated after the encryption of the identification watermark is finished, the terminal detects that the encryption of the preset user identification is finished after receiving the prompt information, and the terminal carries out random encoding on the preset user identification to generate the identification watermark so as to enable the identification watermark and the information to be edited to be overlapped.
In this embodiment, the terminal encrypts the user identifier according to a preset rule, so that on one hand, the user can be prevented from maliciously imitating the identifier information of other users, and the user identifier is prevented from being revealed, and on the other hand, the terminal can analyze the user identifier information only by being used for decoding the secret key, and the security of the identifier watermark corresponding to the user identifier information is ensured.
The present embodiment of the present invention is further provided on the basis of the first embodiment of the present invention, where the refinement of step S40 in the first embodiment specifically illustrates the setting manner of the location of the identification watermark.
Specifically, referring to fig. 4, step S40 in the information security processing method includes:
step S41, the size of the information to be edited and the size of the identification watermark are obtained, the relative size proportion of the information to be edited and the identification watermark is obtained, and whether the relative size proportion accords with the preset proportion is judged.
The method comprises the steps that a terminal obtains the size of information to be edited and the size of a mark watermark to obtain the relative size of the information to be edited and the size of the mark watermark, wherein the size of the information to be edited and the size of the mark watermark can refer to corresponding side length information, the size of the information to be edited and the area of the mark watermark can also be the size of the information to be edited, the relative size of the information to be edited and the size of the mark watermark is determined according to the size of the information to be edited and the size of the mark watermark, for example, the size of the information to be edited is 20cmx10cm, the size of the mark watermark is 5cmx5cm, the relative size of the information to be edited and the area of the mark watermark obtained by the terminal is 8:1, and the terminal judges whether the relative size accords with a preset proportion or not.
The preset proportion is a preset proportion, and the preset proportion can be set to be 10:1, or other preset proportions are set to ensure that the size of the information to be edited is larger than that of the identification watermark, and ensure that the information of the identification watermark is complete and clear.
And step S42, if the relative size proportion is matched with the preset proportion, placing the identification watermarks according to a preset arrangement rule, and carrying out superposition processing on the information to be edited and the identification watermarks.
If the terminal determines that the relative size proportion is matched with the preset proportion, the terminal sets the corresponding positions of the identification watermarks according to a preset arrangement rule (the preset arrangement rule refers to the arrangement rule of the positions of the identification watermarks set according to the proportion, for example, the relative area proportion is 9:1, and the corresponding arrangement rule in the preset arrangement rule is 9 palace), so that superposition processing of the information to be edited and the identification watermarks is completed.
Further, the step of superposing the information to be edited and the identification watermark includes:
after the files with the display watermark images are formed according to the preset arrangement rules, overlapping the arranged identification watermarks with the information to be edited, namely, determining the frequency spectrums of the identification watermarks and the frequency spectrums of the information to be edited, wherein the frequency spectrums are patterns with the amplitudes arranged according to the frequencies, the x-axis is the frequency, the y-axis is the amplitude, overlapping the frequency spectrums of the identification watermarks and the frequency spectrums of the information to be edited, so that the identification watermarks are invisible on the information to be edited, and corresponding transmitting information is obtained. It should be noted that, the user may set the spectrogram according to the actual situation, and select the required frequency and amplitude.
And step S43, if the relative size proportion is not matched with the preset proportion, displaying prompt information for the user to adjust the size of the identification watermark, placing the adjusted identification watermark according to a preset arrangement rule, and carrying out superposition processing on the information to be edited and the identification watermark.
If the relative size proportion is not matched with the preset proportion, prompt information is displayed for the user to adjust the size of the identification watermark, for example, the terminal displays that the identification watermark cannot be completely displayed on the information to be edited and the user reduces the identification watermark according to the prompt information. When the identification watermark meets the requirement, a prompt message is displayed to prompt a user to stop adjusting the identification watermark, after the terminal detects that the size adjustment of the identification watermark is finished, the terminal places the identification watermark according to a preset arrangement rule, and carries out superposition processing on the information to be edited and the identification watermark.
In this embodiment, a method for determining the position of the identification watermark according to the size of the identification watermark and the size of the information to be edited is specifically described, so that the identification watermark is completely and clearly displayed.
Further, referring to fig. 5, on the basis of the first embodiment of the present invention, a second embodiment of the information security processing method of the present invention is proposed, in which an encoded image is generated on a display screen of a terminal to prevent information leakage caused by screen photographing;
specifically, the information security processing method includes:
step S60, if the information is in the information protection mode, the current display interface of the display screen is obtained.
And if the terminal is in the information protection mode, the terminal acquires the current display interface of the display screen to judge whether to display the coded image of the user identifier on the display screen of the terminal according to the display information of the display interface of the terminal so as to prevent information leakage caused by screen photographing. Specifically:
step S70, analyzing the current display interface to obtain display information contained in the current display interface, so as to determine whether to start a photographing prevention mode according to the display information; if the photographing prevention mode is started, acquiring a preset user identifier to encode, and generating an encoding graph.
The terminal analyzes the current display interface to obtain display information contained in the current display interface, wherein the current display interface possibly contains different information, such as a document, application software, a program and the like, the document is displayed on the current display interface for illustration, the terminal takes text information in the document as display information, the terminal determines whether to start an anti-photographing mode according to the content of the display information, and if the anti-photographing mode is started, the terminal obtains a preset user identifier for encoding to generate an encoding graph.
Further, referring to fig. 6, the step of determining whether to start the anti-photographing mode according to the display information in step S70 further includes:
step S71, analyzing the current display interface to obtain display information contained in the current display interface, and obtaining a character set in the display information.
The terminal analyzes the current display interface to obtain display information contained in the current display interface, and acquires a character set in the display information, namely, the terminal analyzes the display information corresponding to the current display interface to obtain the display information, wherein the display information can contain image information, character information and the like, and the terminal acquires the character set in the display information.
Step S72, performing traversal matching on the characters in the character set and the sensitive characters in the preset sensitive information base to judge whether the character set contains the sensitive characters or not.
The terminal performs traversal matching on the characters in the character set and the sensitive characters in a preset sensitive information base (the preset sensitive information base refers to preset sensitive characters, the sensitive characters are e.g. financial transaction data and user personal information) so as to judge whether the character set contains the sensitive characters, and if the characters in the character set are matched with the sensitive characters in the preset sensitive information base, the character set contains the sensitive characters; if the characters in the character set are not matched with the sensitive characters in the preset sensitive information base, the character set does not contain the sensitive characters.
Step S73, if the character set contains sensitive characters, determining the sensitivity level of the current display interface according to the quantity of the sensitive characters.
The terminal determines that the character set contains sensitive characters, and determines the sensitivity level of the current display interface according to the number of the sensitive characters, for example, the terminal determines that the sensitivity level is first-level when the number of the sensitive characters is more than 100, determines that the sensitivity level is second-level when the number of the sensitive characters is more than 100-20, and determines that the sensitivity level is third-level when the number of the sensitive characters is more than 20.
Step S74, if the sensitivity level of the current display interface exceeds a preset threshold, starting a photographing prevention mode.
If the sensitivity level of the current display interface of the terminal exceeds a preset threshold (the preset threshold is a preset sensitivity information level critical value, for example, the preset threshold is set as a second level according to specific conditions), for example, the sensitivity level of the current display interface is a first level, the preset threshold is a second level of the sensitivity level, the sensitivity level of the current display interface exceeds the preset threshold, the terminal starts a photographing prevention mode, and if the photographing prevention mode is started, a preset user identifier is acquired to encode, and a coding graph is generated.
Step S80, converting the coding graph into a preset format vector graph, and scattering and distributing the preset format vector graph on a display screen to prevent information leakage caused by photographing.
The terminal converts the coded graphics into a preset format vector diagram (the preset format vector diagram is a vector diagram which can be set according to factors such as the size of a terminal screen, for example, an SVG vector diagram, also called a scalable vector diagram (Scalable Vector Graphics)), and disperses and distributes the preset format vector diagram onto a display screen so as to prevent information leakage caused by photographing, for example, a graphic creation layer above a current display interface, so that the generated preset format vector diagram is displayed on the graphic creation layer, and an effect that the preset format vector diagram is distributed onto the display screen is generated.
It should be noted that the technical solution in this embodiment may be combined with the technical solution in the first embodiment, that is, the vector diagram is generated on the terminal display screen, and the watermark image is generated on the electronic information sent by the user.
In this embodiment, the user identifier corresponding vector diagram is displayed on the display screen of the terminal according to the current interface display information of the terminal, so that on one hand, leakage of terminal display information caused by photographing of the user can be prevented, and on the other hand, if the display information on the terminal does not relate to sensitive information, the user identifier corresponding vector diagram is not displayed on the display screen of the terminal, so that the user can use the terminal conveniently, convenience in use is considered for the user in this embodiment, and humanized information protection is realized in consideration of safety of information leakage.

specifically, the information security processing method includes:
step S90, when the analysis request triggered based on the transmission information is detected, the transmission information is subjected to Fourier transformation.

And step S100, when the completion of Fourier transform of the transmitted information is detected, acquiring the identification watermark contained in the transmitted information, and decoding the identification watermark to obtain the user identification corresponding to the identification watermark.
When detecting that fourier transform of the transmission information is completed, the terminal acquires the identification watermark contained in the transmission information and decodes the identification watermark to obtain the user identification corresponding to the identification watermark, and it should be additionally explained that the step of information analysis in this embodiment is an inverse process of adding the watermark in the information in the first embodiment, so as to display the user identification information in the information and determine the source of information leakage.
