Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The screen capturing monitoring method provided by the embodiment of the invention can be applied to an application environment shown in figure 1. Specifically, the screen capturing monitoring method is applied to a screen capturing monitoring system, the screen capturing monitoring system comprises a client and a server as shown in fig. 1, and the client and the server communicate through a network to solve the problem of inaccurate monitoring of screen capturing images. The client is also called a user end, and refers to a program corresponding to the server end for providing local service for the client. The client may be installed on, but is not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices. The server may be implemented by a stand-alone server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, a screen capturing monitoring method is provided, and the method is applied to the server in fig. 1 for illustration, and includes the following steps:
s10: and monitoring the operation instruction of the client in real time.
The operation instruction of the client refers to an instruction generated by operation behaviors executed by a user on the client. For example, after the user performs an operation behavior such as touching, clicking, sliding, framing, or screen capturing, the client forms a corresponding operation instruction. The client may be a computer terminal or a mobile terminal, etc. Optionally, the operation instruction of the real-time monitoring client can monitor the operation behavior of the user on the client page in real time by inserting a monitoring script plug-in on the client page. When the monitoring script plug-in monitors the operation behavior of the user on the client page, a corresponding operation instruction is generated in real time, and the operation instruction is sent to the server in real time. In addition, the operation behaviors of the user at the client can be monitored in real time through the computer behavior supervision system or the monitoring platform, corresponding operation instructions are generated, and the operation instructions are sent to the server in real time.
S20: and if the operation instruction is a screen capturing instruction, acquiring a screen capturing image corresponding to the screen capturing instruction.
The screen capturing instruction refers to an instruction generated after a user executes screen capturing action on a client. The screen capturing image refers to an image generated by a user after the client performs a screen capturing action. Specifically, the user may take a screen shot of the entire screen at the client, or take a screen shot of a portion of the screen at the client. Alternatively, the screen capture image may be one or more. Specifically, if the operation instruction sent by the client is a screen capturing instruction, the server acquires a screen capturing image corresponding to the screen capturing instruction.
S30: and detecting information of the screen capturing image and judging whether the screen capturing image contains sensitive information or not.
The sensitive information refers to preset information inconvenient to leak or disclose. For example: the sensitive information may be personal information, financial data, or information related to confidential documents, etc. In a specific embodiment, the server is preset with a custom sensitive information base specially used for storing sensitive information. Specifically, performing information detection on the screen capturing image includes: and carrying out information identification on the screen capturing image by adopting a character identification tool, acquiring corresponding information to be verified from the screen capturing image, and then judging whether the acquired information to be verified contains sensitive information or not. Optionally, judging whether the information to be verified contains sensitive information or not, and matching the information to be verified with sensitive information pre-stored in a user-defined sensitive information base one by adopting a character string matching algorithm; or adopting a regular matching method to match the information to be verified with the pre-stored sensitive information in the user-defined sensitive information base one by one. If the information to be verified is successfully matched with the sensitive information pre-stored in the custom sensitive information base, the screen capturing image is indicated to contain the sensitive information, and if the information to be verified is failed to be matched with the sensitive information pre-stored in the custom sensitive information base, the screen capturing image is indicated to not contain the sensitive information.
S40: and if the screen capturing image contains sensitive information, monitoring the operation behavior of the client on the screen capturing image in real time.
Specifically, if it is determined in step S30 that the screen capturing image includes sensitive information, the operation behavior of the user on the screen capturing image at the client is monitored in real time. In the step, the leakage of the screen capturing image containing sensitive information can be prevented by monitoring the operation behavior of the client on the screen capturing image in real time.
In a specific embodiment, if it is determined in step S30 that the screen capturing image does not include sensitive information, the operation of the monitoring client on the screen capturing image is canceled. On the premise of ensuring the information security of the screen capturing image, background service resources can be saved.
S50: judging whether the operation behavior of the client side on the screen capturing image is illegal or not, and if the operation behavior of the client side on the screen capturing image is illegal, sending early warning information to the client side.
Where an illegal action refers to an action of performing an illegal operation on a screen shot image containing sensitive information. For example: the illegal action may be to send/share the screen shot image containing the sensitive information to a non-permitted person or to save the screen shot image containing the sensitive information to a non-designated file; or printing a screen capturing image containing sensitive information; or posting a screen shot image containing sensitive information to a bulletin web site, etc.
Judging whether the operation behavior of the client side on the screen capturing image is illegal or not, and if the operation behavior of the client side on the screen capturing image is illegal, sending early warning information to the client side. The early warning information is information for prompting a user to operate the screen capturing image as illegal actions. Specifically, the early warning information includes sensitive information contained in the screen capturing image to be highlighted, and option information for prompting a user whether to cancel the operation of the screen capturing image.
Specifically, whether the operation behavior of the client on the screen capturing image is illegal or not is judged, and whether the operation behavior of the client on the screen capturing image is illegal or not can be judged by acquiring instruction information generated by the operation behavior of the client on the screen capturing image. It can be understood that after the client performs any operation on the screen capturing image, the user generates corresponding instruction information, and the server acquires the instruction information sent by the client, then performs information identification on the instruction information, and judges whether the instruction information is illegal instruction information; if the instruction information is identified as illegal instruction information, judging the corresponding operation behavior as illegal behavior. Otherwise, the legal action is performed. The illegal instruction information refers to preset information for detecting whether the operation behavior of the client on the screen capturing image is illegal or not.
In a specific embodiment, if the operation behavior of the client on the screen capturing image is judged to be legal, the early warning information is not sent to the client, and the subsequent operation behavior of the client on the screen capturing image is continuously monitored, so that sensitive information leakage can be further prevented.
S60: and if the revocation instruction of the client to the illegal action is not received within the preset time, executing the locking operation.
Specifically, if the client return revocation instruction is not received within the preset time, the locking operation is executed. Wherein the preset time refers to a time period for canceling the operation behavior on the screen capturing image to the user. Alternatively, the preset time may be set to 5s, 10s, 30s, 45s, 60s, or the like. It will be appreciated that the user may undo the action of manipulating the screen capture image within a preset period of time. And if the user does not cancel the operation behavior of the screen capturing image within the preset time period, namely, the server side does not receive the cancel instruction returned by the client side, executing the locking operation. Optionally, because the client in the solution may be a computer terminal/mobile terminal, performing the locking operation may be locking the computer terminal/mobile terminal, locking some functions of the computer terminal/mobile terminal, or locking some specific application programs on the computer terminal/mobile terminal. For example: the network connection of the computer terminal/mobile terminal can be automatically disconnected, or a mailbox on the computer terminal/mobile terminal is locked, so that the screen capturing image carrying the sensitive information cannot be leaked outwards.
In a specific embodiment, if the revocation instruction returned by the client is received within a preset time, the locking operation is not executed, so that the user can normally execute other operations on the page of the client.
In this embodiment, the operation instruction of the client is monitored in real time; if the operation instruction is a screen capturing instruction, acquiring a screen capturing image corresponding to the screen capturing instruction; detecting information of the screen capturing image, and judging whether the screen capturing image contains sensitive information or not; if the screen capturing image contains sensitive information, monitoring the operation behavior of the client on the screen capturing image in real time; judging whether the operation behavior of the client side on the screen capturing image is illegal or not, if the operation behavior of the client side on the screen capturing image is illegal, sending early warning information to the client side, and if the withdrawal instruction of the client side on the illegal behavior is not received within the preset time, executing locking operation; whether the screen capturing image contains sensitive information or not is detected in real time, and if the screen capturing image contains the sensitive information, a user is reminded to cancel, so that leakage of the sensitive information in the screen capturing image is avoided, and accuracy of monitoring the screen capturing behavior is guaranteed.
In one embodiment, as shown in fig. 3, the information detection is performed on the screen capturing image to determine whether the screen capturing image contains sensitive information, which specifically includes the following steps:
S301: and carrying out information identification on the screen capturing image to obtain information to be verified in the screen capturing image.
The information to be verified refers to information contained in the screen capturing image. Specifically, a character recognition tool (such as OCR character recognition software) preset by the server may be used to perform information recognition on the acquired screen capturing image, so as to acquire the information to be verified included in the screen capturing image. The character recognition tool is used for recognizing characters in the picture. The character recognition tool in the embodiment can adopt OCR character recognition software, and the OCR character recognition software has the advantage of high recognition accuracy.
S302: and matching the information to be verified with preset sensitive information in the sensitive information database to obtain a matching result.
The sensitive information database is a preset database containing a plurality of preset sensitive information. The user can preset a preset quantity of preset sensitive information in the client according to preset requirements, and then the preset sensitive information is stored in a sensitive information database of the server.
Specifically, after the information to be verified in the screen capturing image is obtained, matching the information to be verified with preset sensitive information in a sensitive information database to judge whether the sensitive information exists in the information to be verified; and if the sensitive information exists in the information to be verified, obtaining a matching result as successful matching. Otherwise, if the sensitive information does not exist in the information to be verified, the matching result is obtained as the matching failure.
In a specific implementation method, whether sensitive information exists in the information to be verified or not is judged, and the sensitive information can be set according to a preset standard or mode. Specifically, the preset sensitive information may be set to include specific sensitive information and general sensitive information. Firstly, after the information to be verified in the screen capturing image is obtained, inquiring the information to be verified by adopting a specific character string or a preset field according to the characteristics of special sensitive information, and recognizing that the sensitive information exists in the information to be verified as long as the specific character string or the preset field appears in the information to be verified. For example: the mobile phone number, the bank card number and the identity card number can be regarded as special sensitive information; specific fields may also be identified as particularly sensitive information such as a user name, user address, or amount. Then, matching the information to be verified with the common sensitive information in the sensitive information database one by adopting a character string matching method, and if the information which is the same as the common sensitive information is not matched in the information to be verified, indicating that the common sensitive information is not contained in the information to be verified; if the information which is matched with the common sensitive information in the information to be verified is the same as the common sensitive information, the information to be verified contains the common sensitive information.
Preferably, in order to improve accuracy of the matching result, a matching threshold value may be preset, and if the number of the information matched with the common sensitive information in the information to be verified is greater than the matching threshold value, the information to be verified contains the common sensitive information; if the number of the information which is matched with the common sensitive information in the information to be verified is equal to or smaller than the matching threshold value, the information to be verified does not contain the common sensitive information. Wherein, the matching threshold refers to a critical value for judging whether the information to be verified contains common sensitive information. The matching threshold value can be 20%, 30% or 50%, etc., and the user can customize the setting according to the actual situation.
S303: if the matching result is that the matching is successful, judging that the screen capturing image contains sensitive information.
Specifically, if the matching result obtained in step S302 is that the matching is successful, it is determined that the screen capturing image includes sensitive information.
S304: if the matching result is that the matching fails, judging that the screen capturing image does not contain sensitive information.
Specifically, if the matching result obtained in step S302 is that the matching fails, it is determined that the screen capturing image does not include sensitive information.
In the embodiment, information to be verified in the screen capturing image is obtained by carrying out information identification on the screen capturing image; matching the information to be verified with preset sensitive information in a sensitive information database to obtain a matching result; if the matching result is that the matching is successful, judging that the screen capturing image contains sensitive information; if the matching result is that the matching fails, judging that the screen capturing image does not contain sensitive information; the efficiency and the accuracy of detecting the screen capturing image are guaranteed.
In an embodiment, as shown in fig. 4, after acquiring the screen capturing image corresponding to the screen capturing instruction if the operation instruction is the screen capturing instruction and before detecting the information of the screen capturing image, the screen capturing monitoring method further includes the following steps:
s21: and determining the screen capturing page where the screen capturing image is located.
The screen capturing page refers to a page where a user executes screen capturing operation behaviors. For example: when a user logs in a certain application program, screen capturing operation is carried out on a login page in the application program to generate a screen capturing image, and the login page is the screen capturing page where the screen capturing image is located.
S22: and judging whether the screen capturing page belongs to the sensitive page according to the application program to which the screen capturing page belongs.
Where a sensitive page refers to a page that may contain sensitive information. The sensitive page may be a page where a strong application within the company is located. For example: pages where applications related to corporate operation reports are located, pages where applications related to corporate internal information are located, etc. In this embodiment, the application includes, but is not limited to, app software.
Optionally, the application program to which the determined screen capturing page belongs may perform page detection on the screen capturing page through a page detection tool, so as to determine whether the screen capturing page has a display identifier specific to a certain application program. Alternatively, the application-specific display identifier may be a logo identifier of the application. Or by detecting which applications running in the foreground when performing the screen capture operation are included. For example: and if the application program corresponding to the Foxmail runs in the foreground when the screen capturing operation is detected, judging that the application program to which the screen capturing page belongs is the Foxmail.
After determining the application program to which the screen capturing page belongs, a state management policy of one application program can be preset, wherein the state management policy comprises each application program and a corresponding state identifier. Wherein the status identifications include sensitive identifications and non-sensitive identifications. In a particular embodiment, each application is pre-associated with a corresponding state identification. For example: applications within the company that are strong in confidentiality are associated with sensitive identities, and some applications that are not critical are associated with non-sensitive identities. Specifically, after the screen capturing page is acquired, an application program to which the screen capturing page belongs is determined, then a corresponding state identifier is acquired according to the application program, if the acquired state identifier is a sensitive identifier, the screen capturing page is judged to belong to the sensitive page, and if the acquired state identifier is a non-sensitive identifier, the screen capturing page is judged to belong to the non-sensitive page. It can be appreciated that if the acquired screen capture page is not in any application program, the screen capture page is directly judged to belong to a non-sensitive page.
S23: and if the screen capturing page belongs to the sensitive page, executing information detection on the screen capturing image.
Specifically, if it is determined in step S22 that the screen capturing page belongs to the sensitive page, the step of detecting information of the screen capturing image is triggered.
In a specific embodiment, if it is determined in step S202 that the screen capturing page does not belong to the sensitive page, the step of detecting information of the screen capturing image is not performed, but a preset general monitoring module is started to monitor the operation behavior of the client, and in the general monitoring mode, if the behavior of the client is monitored to be an abnormal legal behavior, early warning information is sent to the client, and the alert user is revoked. If the monitored behavior of the client is the normal legal behavior, no early warning information is sent to the client, and the subsequent operation behavior of the client on the screen capturing image is monitored in the normal monitoring mode. Where the normal legal action may be to place the screenshot image in a designated folder or to send the screenshot image to a specific user. The non-common legal action may be copying and pasting the screenshot image into a non-designated file or sending the screenshot image to an outside person.
In the embodiment, the screen capturing page where the screen capturing image is determined; judging whether the screen capturing page belongs to a sensitive page according to an application program to which the screen capturing page belongs; if the screen capturing page belongs to the sensitive page, executing information detection on the screen capturing image; before information detection is carried out on the screen capturing images, the page where the screen capturing images are located is judged to belong to a sensitive page, and information detection is carried out on the screen capturing images corresponding to the sensitive page, so that the burden of a background system is reduced, and the accuracy of monitoring the screen capturing behaviors is improved. In an embodiment, as shown in fig. 5, the method for determining whether the operation line of the client on the screen capturing image is illegal specifically includes the following steps:
S501: and if the operation behavior of the client to the screen capturing image is the interaction behavior, acquiring the client identifier.
The client identifier refers to an identity information identifier of a user performing operation behaviors at the client. Alternatively, the client identifier may be a mobile phone number, a job number, or an identification card number of the user, which represents unique identity information of the user. In a specific embodiment, the user performing the operation behavior at the client may be a user corresponding to the login of the operating system, or may be a user corresponding to the login of the specified application program. If the user performing the operation on the client is a user corresponding to the user logging in the designated application, the client label may correspond to login information of the user logging in the application. Specifically, if the operation behavior of the client on the screen capturing image is monitored to be the interaction behavior, the client identification is directly obtained.
S502: and acquiring the interactive authority level of the user according to the client identification.
The interaction permission level refers to the permission level of the user to interact with the screen capturing image. For example: permission level for transmitting the screen shot image. Specifically, different users have different interaction authority levels, for example, a common staff only has viewing authority on a screen shot image and cannot perform sending operation, a middle-layer manager only has sending authority on a designated receiving end, and a high-layer manager has sending authority on any receiving end. In one embodiment, different client identifications have been previously associated with corresponding interaction rights levels and stored in a database. After the client identifier is obtained, the corresponding user interaction permission level can be directly obtained from the database according to the client identifier. In this embodiment, the interactive authority level of the user is determined through the client identifier, different authorities of different users are divided, and the use requirements of different users can be met while the security of the screen capturing image is ensured.
S503: and if the interaction permission level meets the preset permission level, acquiring a receiving end identifier corresponding to the interaction behavior.
The preset permission level refers to a standard for judging whether a user has specific interaction permission on the screen capturing image. Alternatively, the preset authority level may be set such that the middle-level manager and the high-level manager have interactive authority on the screen shot image. Specifically, if the interaction permission level of the acquired user is the middle-layer manager according to the client identifier, that is, the preset permission level is met, the receiving end identifier corresponding to the interaction behavior is acquired. The receiving end identification refers to an identification corresponding to another terminal for receiving the screen capturing image. In a specific embodiment, before the user performs the interaction on the screen capturing image, the receiving terminal performing the interaction needs to be determined or selected, so if the interaction permission level of the user is determined to meet the preset permission level, the receiving terminal identifier corresponding to the interaction behavior can be directly obtained from the client. Alternatively, the receiving end identifier may be a terminal name, an IP address, or a network card number of the receiving terminal.
S504: judging whether the receiving end identifier is in a preset authority identifier or not, and if the receiving end identifier is not in the preset authority identifier, determining that the operation behavior of the client on the screen capturing image is illegal.
The preset permission identification refers to a preset terminal identification number capable of receiving the screen capturing image. For example: the preset permission identification can be a terminal identification number corresponding to personnel in the company or a preset specific terminal identification number. In a specific embodiment, the database of the server side stores a plurality of preset authority identifiers in advance. Specifically, whether the receiving end identifier is in the preset authority identifier is judged, the obtained receiving end identifier can be matched with the preset authority identifier stored in the database one by one, and if the obtained receiving end identifier is not matched with all the preset authority identifiers stored in the database, the receiving end identifier is not in the preset authority identifier. Otherwise, if the obtained receiving end identifier is matched with any preset authority identifier stored in the database in advance, the receiving end identifier is indicated to be in the preset authority identifier.
In a specific embodiment, if the receiving end identifier is not within the preset authority identifier, the operation behavior of the client on the screen capturing image is determined to be illegal.
In this embodiment, if the operation behavior of the client to the screen capturing image is an interaction behavior, the client identifier is obtained; acquiring the interactive authority level of the user according to the client identifier; if the interaction permission level meets the preset permission level, acquiring a receiving end identifier corresponding to the interaction behavior; judging whether the receiving end identifier is in a preset authority identifier or not, and if the receiving end identifier is not in the preset authority identifier, determining that the operation behavior of the client on the screen capturing image is illegal; the interactive authority level of the user is determined through the client identification, and aiming at the interactive authority level of different users, the security of the screen capturing image is ensured, meanwhile, the use requirements of different users are met, and the user experience is improved.
In one embodiment, as shown in fig. 6, after determining whether the receiving end identifier is within the preset authority identifier, the screen capturing monitoring method further includes the following steps:
s505: if the receiving end identifier is in the preset authority identifier, judging that the operation behavior of the client on the screen capturing image is legal.
Specifically, if the receiving end identifier is judged to be in the preset authority identifier, judging that the operation behavior of the client on the screen capturing image is legal.
S506: and determining the position of the region where the sensitive information is located in the screen capturing image.
Where the location of the region refers to the specific location where the sensitive information is located in the screen capture image. In a specific embodiment, the location of the region of the sensitive information may be represented by a coordinate location in the screen capture image where the sensitive information is located. Alternatively, the position of the area in this embodiment is preferably represented by the center coordinate of the rectangular area in which the sensitive information is located. Specifically, determining the location of the region in the screen capture image where the sensitive information is located can be achieved by using an openCV method.
S507: and blurring the sensitive information of the corresponding region position to obtain a target screen capturing image.
The target screen capturing image refers to an image obtained by blurring sensitive information in the screen capturing image. Specifically, the blurring processing of the sensitive information corresponding to the region position refers to the process of hiding the region position where the sensitive information is located in the screen capturing image in a certain way. Optionally, blurring processing of the sensitive information of the corresponding region position can be automatically realized by means of an image processing tool, or blurring processing of the sensitive information region in the screen capturing image is realized by using java language, so that the target screen capturing image is obtained.
