Detailed Description
in order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
financial APP includes APP that banks, securities, insurance, trust and other financial field companies use, because the data that these APP related to are very important, therefore, how to prevent data from being illegally transmitted is the problem that all companies all pay close attention to, must guarantee user's legitimacy, in case data suffer illegal transmission, need trace to the source to the data of illegal transmission, retrieve the loss of company.
referring to fig. 1, a flowchart of a method for displaying a financial APP interface according to an embodiment of the present invention is shown, where the method for displaying a financial APP interface includes the following steps:
and S100, acquiring the address of the user information database, and associating the address with the user information database.
The user information database is financial APP's third party database, can acquire through the user input address, also can network according to the company name of user input and acquire or download the connection information and acquire, be in the same place user information database and financial APP relevance, as the database at backstage, manage by the company that uses financial APP, when new staff that entries, with this staff's information entry to this user information database, when staff leaves the position, delete from this user information database with the staff that will work, protect this user information database's renewal state.
The information of the employee comprises a user name and a password of the employee for using the financial APP.
The association between the user information database and the financial APP is performed through the address of the database, for example, the user information database of the company A is associated with the financial APP through the database address of the company A, the user information database of the company B is associated with the financial APP through the database address of the company B, when the employee of the company A logs in the financial APP, the user information database of the company A is associated with the APP, and when the employee of the company B logs in the APP, the user information database of the company B is associated with the APP.
step S101, when a user logs in a financial APP, login information of the user is obtained.
When a user logs in the financial APP through a login interface of the financial APP, the financial APP acquires information input by the user, specifically, a user name and a password input by the user at the login interface of the financial APP, and the user name and the password are used for being compared with an associated user information database.
step S102, judging whether the login information exists in the user information database.
After obtaining the information input by the user, the financial APP compares the information with a user information database of a company selected by the user, and if the user login information has unique data corresponding to the unique data in the user information database, the user is judged to be in the user information database and is a legal user of the company; if the user login information does not have data corresponding to the user login information in the user information database, the user login information is judged to be not in the user information database, and the user is an illegal user of the company or a user who does not open the authority in the company.
and step S103, if the login judgment result is that the user information does not exist in the user information database, refusing to login the financial APP.
specifically, if the login judgment result is that the user information does not exist in the user information database, the user is judged to be an illegal user or a user who does not open the authority, the user is refused to login the financial APP, the user cannot acquire related data of the financial APP, the legality of the user is guaranteed, and the illegal user is prevented from acquiring data information of a company and causing loss to the company.
And step S104, if the login judgment result is that the user information exists in the user information database, generating watermark information according to the login information, and embedding the watermark information into an interface of the financial APP to generate interface data with the watermark.
Specifically, if the login judgment result indicates that the user information exists in the user information database, the user is judged to be a legal user, the user is allowed to log in, and after the login is successful, the financial APP generates watermark information according to the login information of the user, wherein the watermark information includes but is not limited to the following modes:
1. and generating watermark information according to the company information and the user name of the user, wherein the company information is used as display content which can be identified by naked eyes, and the user name is used as watermark content which cannot be seen by naked eyes. The information of the company may be short name of the company or LOGO, for example: "xx company" in this way, when using APP, the user only sees the information of the company, but cannot see the information of the user, and thus, the user is prevented from actively attacking the watermark, such as altering after screen capture, and the like, to shield the information of the watermark, and then illegal transmission of data is performed.
2. Generating watermark information according to the company information, the user name and the login time of the user, wherein the company information is used as display content which can be identified by naked eyes, and the user name and the login time are used as watermark content which cannot be seen by naked eyes. Therefore, when the watermark is extracted, the login time information of the user can be extracted, the illegal transmission data can be traced and traced, and the tracing efficiency and precision are improved.
Referring to fig. 2, another flowchart of a display method of a financial APP interface according to an embodiment of the present invention is shown, specifically, the embedding of the watermark information into the financial APP interface in step S104 includes the following steps:
and step S1041, generating a label according to the watermark information.
and encrypting the watermark information by a preset key to generate a corresponding watermark ciphertext, and generating a corresponding label according to the watermark ciphertext.
Specifically, the generated tag includes two parts: a plaintext part and an encrypted part. The plaintext part is the information of the company, and is directly displayed as the plaintext, such as: "xx company", a plain text label is generated based on "xx company". The encryption part includes: and encrypting the watermark information based on the preset key to obtain a corresponding watermark ciphertext and generating a corresponding label based on the watermark ciphertext by using the user information such as the user name, the login time and the like. Therefore, the watermark seen by the user is only the plaintext part, but the encrypted part cannot be seen by the user, and the illegal transmission of the data can be prevented from being carried out due to active attack on the watermark to a great extent.
In practical application, if the obtained watermark information needs to be kept secret, the obtained watermark information needs to be encrypted by an Encryption algorithm, such as an Advanced Encryption Standard (AES) algorithm, based on a preset key, and then is encoded by an encoding algorithm, such as a Base64 algorithm, to generate a corresponding watermark ciphertext, and then generates a corresponding label based on the watermark ciphertext. Therefore, when a user browses a file, the user cannot visually acquire the watermark information before encryption through the displayed label, and the purpose of watermark encryption is achieved.
for example: when the user name information 'zhang san' is encrypted, the watermark information can be encrypted based on a preset key, then coding is carried out to obtain a string of character string watermark ciphertext 'ABC', a corresponding label is generated based on the watermark ciphertext, a user sees the watermark ciphertext obtained after the watermark information is encrypted when using the APP, and the user cannot visually know the watermark information before encryption.
in case of data being illegally transmitted and watermark information needing to be extracted, the watermark ciphertext can be decoded through an encoding and decoding algorithm such as Base64, and then decrypted through an encryption and decryption algorithm such as an AES algorithm to obtain corresponding watermark information, so that an illegal transmitter can be traced.
For example, the encrypted watermark information is "CDF", and is decoded by a decoding algorithm, and decrypted by a decryption algorithm to obtain the decrypted watermark information which is "lie four".
further, in the process of generating the label, the transparency of the label can also be set.
For example: the user sets the attribute of the label and sets the transparency bit of the label to be 90%.
by setting the transparency of the label, a user can not be influenced by the label when browsing the APP.
Step S1042, add the label to the preset map layer.
The preset image layer covers the whole APP interface for the size matched with the screen of the mobile phone of the user, the image layer is divided into N multiplied by N areas, the value of N can be set, and is optimal, the value of N is larger than 3, therefore, the data in each area of the financial APP can be guaranteed to have watermark information, and the effects of protecting data safety and tracing are achieved.
For example, if N is 4, the preset image layer is divided into 16 regions, that is, the interface corresponding to the financial APP is also divided into 16 regions, and all of the 16 regions have watermark information, so that it is difficult for a user to illegally transmit data of a certain region by means of screen capture, because at least 1 complete watermark information is likely to be included in the screen capture region.
And step S1043, overlapping the layer and the APP data for presentation.
Specifically, the attribute parameters of the layer may be adjusted first; and then, placing the adjusted layer above the APP interface to enable the layer and the APP interface to be displayed in an overlapping mode.
When adjusting the attribute parameters of the layer, at least one or any combination of the following parameters is adjusted: the image layer shape, the image layer transparency, the image layer center coordinate and the image layer rotation angle.
For example, adjusting attribute parameters of the layer, setting the shape of the layer as a rectangle, the transparency of the layer as 80%, the center coordinate of the layer as the center of the screen, and the rotation angle of the layer as 0 degree.
The required coverage effect of the image layer is achieved by setting the position, the shape, the transparency and the like of the image layer.
In addition, the layer after adjusting is arranged above the finance APP interface, so that the layer and the APP interface are overlapped and displayed, and thus, a user can see the layer and the APP interface simultaneously.
Further, when it is determined that the user instructs to perform scrolling, page turning, or zooming operations on the APP interface, in order to ensure that the tag always covers the financial APP interface, the following two ways may be adopted, but are not limited to:
The first method is as follows: and when the user is determined to indicate that the APP interface is scrolled, paged or zoomed, keeping the position and the display content of the layer unchanged.
By adopting the first mode, when the APP interface is scrolled, turned or zoomed, the central coordinate of the layer and the rotation angle of the layer are kept unchanged, the number of the labels in the layer is always unchanged, and the labels in the layer are arranged according to the preset N multiplied by N arrangement mode all the time, so that the labels in the layer can cover the screen according to the preset N multiplied by N arrangement mode all the time.
The second method comprises the following steps: when the fact that a user indicates to perform scrolling or page turning operation on the APP interface is determined, synchronously scrolling and page turning are performed on the layer and the APP interface, the number of labels currently displayed in the layer is detected, and the labels in the layer are additionally added in an N multiplied by N arrangement mode based on a detection result; when it is determined that the user indicates to perform scaling operation on the APP interface, the layer and the APP interface are synchronously scaled, the number of currently displayed labels in the layer is detected, and the labels in the layer are additionally added by adopting an NxN arrangement mode based on a detection result.
For example: arranging the labels in the layer in a 4 × 4 matrix manner, setting the size of the layer as the size of the whole screen, when determining that a user indicates to perform a rolling operation on the APP interface, synchronously rolling the layer and the APP interface, detecting the number of the labels currently displayed in the layer, and supplementing and adding 4 labels to corresponding positions in the layer in a 4 × 4 arrangement manner when the number of the labels in the layer is less than 4 × 4, if the number of the labels remaining in the layer is 3 × 4, and recovering the number of the labels to 16; another example is: when it is determined that the user indicates to perform page turning operation on the APP interface, the number of the remaining tags in the layer is 0 x 0, adding the 16 tags to corresponding positions in the layer in a 4 x 4 arrangement manner, and recovering the number of the tags to 16; for another example, when it is determined that the user instructs to perform the enlarging operation on the APP interface, and the number of the remaining tags in the layer is 3 × 3, 7 tags are complementarily added to corresponding positions in the layer in a 4 × 4 arrangement manner.
And by adopting the second mode, the labels displayed in the layer are arranged in an NxN arrangement mode all the time, so that the coverage rate of the labels in the layer on the financial APP interface is ensured.
Through above three steps, with watermark information embedding to finance APP interface, make APP interface data combine together with the watermark, played the purpose that prevents APP data by illegal transmission.
according to the display method of the financial APP interface provided by the embodiment of the invention, the login information of the user is compared with the APP associated user information database, an illegal user is rejected, the legality of the financial APP user is ensured, meanwhile, the watermark information is generated according to the information of the user, and the watermark information is generated into plaintext and ciphertext to be embedded into the APP interface through the secret key, so that the user can only see the plaintext watermark information, the possibility that the watermark is attacked and damaged is reduced, in case that the data is illegally transmitted, the source tracing can be carried out on an illegal transmitter, and the safety of the financial APP data is improved.
On the basis of the former embodiment, when a user forwards a financial APP interface data file, the watermark information on the interface data is decrypted, the user information of the watermark is extracted, whether the user information accords with the use authority or not is checked, if not, the user is prohibited from forwarding the data, and if the user information accords with the use authority, the interface data is decrypted, and the user is permitted to forward the data.
In the practical application of financial APP, for reasons such as communication in work, forwarding operation needs to be performed on APP interface data, for example, the APP interface data is forwarded to a mail or other communication tools; in addition, the data of the financial APP interface has different operation permissions for different users, common users, namely common employees, do not have the permission to forward the data, and users above a senior level use supervisor level have the permission to forward the data; or the staff of each branch of the company can check the data information of the whole company, but only the branch information of the company can be forwarded. For example, a company has a Shenzhen subsection and a Guangzhou subsection, and then a certain employee of the Shenzhen subsection can view data of both the Shenzhen subsection and the Guangzhou subsection, but can only forward data of the Shenzhen subsection.
Referring to fig. 3, a flowchart of a display method of a financial APP interface provided in an embodiment of the present invention is shown, specifically, the monitoring forwarding operation of the user includes the following steps:
And step S200, the user requires to forward the financial APP interface data.
The user can select the instruction of forwarding at the financial APP interface according to own needs, and the financial APP receives the instruction that the user requires to forward financial APP interface data at this moment.
Step S201, extracting watermark information of a financial APP interface.
When the financial APP receives an instruction that a user requires to forward financial APP interface data, the financial APP extracts watermark information in a preset layer, decodes the watermark ciphertext through a coding and decoding algorithm such as Base64, and then decrypts through an encryption and decryption algorithm such as an AES algorithm to obtain corresponding watermark information.
Step S202, judging whether the user accords with the use authority.
Specifically, after the watermark information is acquired, the information related to the user is acquired, the grade or the company part of the user is verified, and if the user is judged to be a common user or the user part is different from the company part to which the financial APP interface data belongs, the user is judged not to conform to the use permission; and if the user is judged to be a high-level user and the part of the company to which the APP interface data belongs is the same, judging that the user accords with the use permission.
Step S203, if the user does not accord with the use authority, the forwarding operation of the user is forbidden.
Specifically, if the judgment result after the user information is extracted indicates that the user does not accord with the use right, the user is prohibited from forwarding, so that the threshold of data safety is improved, and the safety of financial APP interface data is further improved.
And step S204, if the use authority is met, allowing the forwarding operation of the user.
Specifically, if the judgment result after the user information is extracted is that the user accords with the use right, the user is allowed to forward the operation, specifically, the data on the financial APP interface is decrypted first, the permission of transferring is released, the user can forward the operation, and the user of the financial APP is provided with the convenience in use.
according to the display method of the financial APP interface provided by the embodiment of the invention, through the verification of one authority of the user requiring to forward the financial APP interface data, the user who does not conform to the use authority is prevented from performing forwarding operation on the APP interface data, and the possibility that the data is illegally transmitted is further reduced. Meanwhile, the APP user conforming to the use authority is allowed to carry out forwarding operation, and convenience is brought to work of the user.
On the basis of the former embodiment, in order to encrypt the forwarded data and prevent the data from being illegally transmitted, the embodiment of the invention adds a watermark to the forwarded APP interface data in a scrambling encryption mode by using the user information, and can trace the source of a transmitter in case of illegally transmitting the data.
Referring to fig. 4, a flowchart of a display method of a financial APP interface provided in an embodiment of the present invention is shown, specifically, the watermarking the forwarded information includes the following steps:
And step S300, generating a watermark matrix according to the watermark information.
In the second embodiment, when the user performs the forwarding operation, the financial APP extracts the watermark information, and after it is determined that the user conforms to the permission of the usage permission to allow the user to perform the forwarding operation, before actual APP interface data is forwarded, the watermark information is represented in a matrix form to generate a watermark matrix.
Step S301, generating a thread relation matrix according to a program corresponding to interface data of the financial APP.
Because the embodiment of the invention is based on the thread relation of the financial APP, and the relations among the threads are of various types, the most suitable relation type can be selected according to the self condition of the financial APP in the actual process, such as the sequence relation of thread execution, the main control relation in the thread execution process and the like. In order to utilize and modify the relationship between threads, the existing thread relationship of the financial APP needs to be obtained, the executing process of the financial APP is monitored through a debugger, the thread relationship of the financial APP is recorded, the thread relationship is numbered, and then a thread relationship matrix is generated according to the numbered thread relationship.
step S302, the arnold transformation scrambling processing is carried out on the thread relation matrix, and a disorder thread relation matrix is generated.
Scrambling the thread relation matrix generated after the financial APP runs, scrambling the thread relation matrix by using Arnold transformation in the embodiment of the invention, and scattering the thread relation matrix.
Step S303, the watermark matrix is embedded into the disordered thread relation matrix, and inverse scrambling processing is carried out to restore the disordered thread relation matrix into a sequential thread relation matrix.
The watermark matrix is embedded into the disordered thread relation matrix, and in order to increase the resistance to malicious attacks, a quantization technology is used to enable a plurality of elements in the thread relation matrix to correspond to one element in the watermark matrix, so that even if the elements in the thread relation matrix are tampered, the watermark data cannot be tampered. In the embodiment of the invention, the parity of the elements in the 4 thread relation matrixes corresponding to the value of one element of the embedded watermark is used. The likelihood of the watermark element having a value of 0 or 1 is the same, so half of the four elements may not need to be modified. Meanwhile, the thread relation matrix mostly belongs to a sparse matrix, namely most values in the thread relation matrix are 0, so that only one 0 of the 4 elements needs to be modified into 1 even if the modification is carried out. And carrying out inverse scrambling on the disorder thread relation matrix embedded with the software watermark matrix, and recovering the disorder thread relation matrix into a sequence thread relation matrix.
And step S304, modifying the source code of the financial APP according to the sequential thread relation matrix, and generating a final program with the watermark.
Because the watermark matrix is embedded in the thread relation matrix, the financial APP is modified to reflect the change of the thread relation matrix, two threads influenced by the watermark matrix are determined by determining the positions of the values of the thread relation matrix, which change before and after the watermark is embedded, codes at corresponding threads in the financial APP source codes are modified according to the selected relation type, and the final program after the watermark is embedded can be obtained after the modification of the threads corresponding to all the variable elements is completed.
Because various conventional changes in the propagation process of the financial APP cannot influence the thread relationship, and simultaneously, the user cannot completely determine the relationship between threads due to the fact that the user does not have a source code of software, the financial APP cannot be normally used due to the fact that the user carries out modification, and therefore the watermark based on the thread relationship has high safety.
According to the financial APP interface display method provided by the embodiment of the invention, the watermark of the thread relation is added to the financial APP information of the forwarding operation, so that the safety of the financial APP data is further improved, and the aim of preventing the data from being illegally transmitted is fulfilled.
