Detailed Description
The principles and spirit of the present invention will be described with reference to a number of exemplary embodiments. It is understood that these embodiments are given only to enable those skilled in the art to better understand and to implement the present invention, and do not limit the scope of the present invention in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
The technical solution of the present invention is further elaborated below with reference to the drawings and the specific embodiments.
Fig. 1 is a schematic diagram illustrating a first implementation flow of a data hiding method according to an embodiment of the present invention.
Referring to fig. 1, a data hiding method according to an embodiment of the present invention is applied to a terminal, and the method includes: operation 101, receiving an open operation instruction for an online spreadsheet document; an operation 102, in response to the opening operation instruction, of initiating a request for opening the online spreadsheet document to a server to instruct the server to perform hiding processing on the content of the sensitive data area existing in the online spreadsheet document according to the user permission; operation 103, receiving the hidden processed online spreadsheet document fed back by the server; and operation 104, calling an online electronic form program to display the hidden online electronic form document on a user interface.
In operation 101, the terminal receives an opening operation instruction of a user with respect to an online spreadsheet document. The opening operation instruction may be a touch opening operation instruction, a button opening operation instruction, or an opening operation instruction of clicking a mouse.
In operation 102, the terminal initiates a request for opening the online electronic form document to the server in response to the opening operation instruction, so as to instruct the server to hide the content of the sensitive data area in the online electronic form document according to the user right. After the server hides the content of the sensitive data area in the online electronic form document according to the user authority, the hidden online electronic form document is fed back to the terminal. In this way, the server feeds back only the hidden processed, rather than the complete, online spreadsheet document to the client, through the user rights.
The hiding processing of the content of the sensitive data area existing in the online electronic form document can be directly filtering the content of the sensitive data area, or can be modifying the content of the sensitive data area into meaningless content.
In operations 103-104, the terminal receives and displays the hidden online spreadsheet document fed back by the server.
According to an embodiment of the present invention, the hiding method further includes, on the basis that the hidden processed online spreadsheet document is displayed in operation 104: displaying the sensitive data area on a user interface; or, the sensitive data area is displayed on a user interface, and corresponding prompt information is displayed. For example, invoking an online spreadsheet program explicitly displays sensitive data areas on the user interface while prompting the user that the form contents of these sensitive data areas are incorrect and are referenced discreetly, directly or indirectly.
Compared with the traditional scheme that the sensitive data is not displayed on the user interface of the graphite document, but all document contents including the sensitive contents are sent to the client side actually, the data hiding method provided by the embodiment of the invention has the advantages that the server only feeds back the hidden and incomplete online electronic form document to the client side through the user authority, so that the terminal user can be effectively ensured not to obtain the sensitive data from the program interface or the network request on the basis of hiding the sensitive data, and the potential data safety hazard of the online electronic form is really avoided.
FIG. 2 is a schematic diagram illustrating a second implementation flow of the data hiding method according to the embodiment of the present invention; fig. 3 shows a third implementation flow diagram of the data hiding method according to the embodiment of the present invention.
Referring to fig. 2, a data hiding method according to an embodiment of the present invention is applied to a server, and the method includes: operation 201, receiving a request for opening an online spreadsheet document from a terminal; operation 202, in response to the opening request, hiding the content of the sensitive data area existing in the online spreadsheet document according to the user authority; and in operation 203, feeding back the online electronic form document subjected to the hiding processing to the terminal, so that the terminal displays the online electronic form document subjected to the hiding processing on a user interface by calling an online electronic form program.
In operations 201-202, after receiving a request for opening an online electronic form document from a terminal, a server hides contents of a sensitive data area in the online electronic form document according to user rights. The hiding processing of the content of the sensitive data area existing in the online electronic form document can be directly filtering the content of the sensitive data area, or can be modifying the content of the sensitive data area into meaningless content.
In operation 203, after the server hides the content of the sensitive data area in the online electronic form document according to the user right, the online electronic form document after being hidden is fed back to the terminal. In this way, the server feeds back only the hidden processed, rather than the complete, online spreadsheet document to the client, through the user rights.
According to an embodiment of the present invention, as shown in fig. 3, the method further includes: operation 301, receiving a modify operation request for an online spreadsheet document; operation 302, in response to the modification operation request, checking whether the modification operation request is a modification of the content of a sensitive data area in the online spreadsheet document; in operation 303, if the modification operation request is directed to the modification of the content of the sensitive data area in the online spreadsheet document, the modification operation request is multicast to an authorized terminal, so as to execute a corresponding modification operation.
Wherein, the modification operation can be a setting operation of adding, modifying or deleting the sensitive data area. Specifically, in order to better guarantee the security problem of the online spreadsheet document, each time a user needs to modify the content of the spreadsheet document, the client sends the modification operation to the server, and then the server is responsible for broadcasting the modification operation to all online users. Of course, before the server broadcasts the modification operation, the server needs to check whether the modification operation is directed to the content of the sensitive data area, and if so, it will multicast the modification operation to those authorized online users so that the authorized online users can perform the corresponding modification operation.
According to an embodiment of the present invention, as shown in fig. 3, the method further includes: operation 304, while multicasting the modification operation request to the authorized terminal so as to execute the corresponding modification operation, hiding the content of the sensitive data area existing in the online spreadsheet document, and broadcasting the modification operation to other online users without authorization after hiding.
Specifically, the server multicasts the modification operation request to the authorized terminal so as to execute the corresponding modification operation, and meanwhile, correspondingly modifies the content of the sensitive data area, such as filtering the content of the modification operation or modifying the content into meaningless content, in order to be responsible for broadcasting the modification operation to all online users; and then, multicasting the modification operation to other online users without authority. Thus, when other online users receive the modification operation, the online spreadsheet program automatically sends a request to the server to retrieve the document content and re-render the online spreadsheet document.
Similarly, based on the data hiding method described above, an embodiment of the present invention further provides a computer-readable storage medium, where a program is stored, and when the program is executed by a processor, the processor is caused to perform at least the following operation steps: operation 101, receiving an open operation instruction for an online spreadsheet document; an operation 102, in response to the opening operation instruction, of initiating a request for opening the online spreadsheet document to a server to instruct the server to perform hiding processing on the content of the sensitive data area existing in the online spreadsheet document according to the user permission; operation 103, receiving the hidden processed online spreadsheet document fed back by the server; and operation 104, calling an online electronic form program to display the hidden online electronic form document on a user interface.
