Description

Technical Field

[0001] The present application relates to the field of intelligent environmental monitoring technology, and in particular to a method, system, device and storage medium for preventing mistransmission and tampering of photos. Background Art

[0002] The operation and maintenance management of ambient air quality monitoring sites is an important part of ensuring the accuracy, timeliness and effectiveness of monitoring data. With the rapid development of information technology, in order to improve the timeliness and standardization of operation and maintenance management, terminal APP and operation and maintenance platform have been launched for online reporting and trace management. Operation and maintenance personnel can carry out site operation and maintenance work and fill in task work orders according to the requirements of operation and maintenance tasks, and collect, store and upload relevant operation and maintenance photos through terminal APP. Afterwards, the auditor will review the operation and maintenance work based on the photos and the content reported by the operation and maintenance personnel, and promptly discover abnormal situations in the operation and maintenance process.

[0003] Site operation and maintenance work is often carried out in geographically remote environments with poor network conditions, and requires frequent collection and uploading of a large number of on-site operation and maintenance photos. In the actual site operation and maintenance photo collection work, operation and maintenance personnel usually temporarily store the site photos taken in the local album of their personal devices, and then upload the site operation and maintenance photos after completing the on-site work and returning to the office or urban areas with better network conditions. Therefore, there may be situations where operation and maintenance personnel mistakenly upload site photos, or process the collected operation and maintenance photos before uploading them in order to conceal problems in the operation and maintenance work, which affects the monitoring data quality of the ambient air quality monitoring site.

[0004] Therefore, it is necessary to propose a solution that can effectively prevent problems such as mistransmission and tampering of photos during the operation and maintenance of environmental air quality monitoring stations. Summary of the invention

[0069] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0070] Figure 1The flowchart of the method for preventing wrong transmission and tampering of photos according to an embodiment of the present application is shown. The method can be used in a mobile terminal, that is, the execution subject of the method can be a mobile terminal, wherein the mobile terminal can be installed with a target APP, and the target APP can be an APP dedicated to the collection and upload of site operation and maintenance photos. Figure 1 As shown, the method may include the following steps:

[0071] S101. Obtain the operation and maintenance task order of the ambient air quality monitoring site through the target APP.

[0072] In one embodiment, the operation and maintenance task work order may include, but is not limited to: unique coding information and first positioning information of the ambient air quality monitoring site.

[0073] As an example, the mobile terminal can obtain the operation and maintenance task work order of the ambient air quality monitoring site distributed by the central end through the target APP. The operation and maintenance task work order can be preset with operation and maintenance task information, as well as the unique coding information and first positioning information of the ambient air quality monitoring site. The user can go to the ambient air quality monitoring site to carry out operation and maintenance and operation and maintenance photo collection according to the operation and maintenance task information in the operation and maintenance task work order.

[0074] In one embodiment, the unique coding information of the ambient air quality monitoring site can be set as a fixed length code according to the coding rules, such as a 9-digit code. Among them, the administrative area code plus an additional three-digit code can be used to ensure the uniqueness of the ambient air quality monitoring site code and the standardization and convenience of management. For example, the unique coding information of the ambient air quality monitoring site can be 110000001.

[0075] In one embodiment, the first positioning information may be GPS positioning information, which may adopt the WGS-84 coordinate system. The first positioning information may include longitude coordinate values ​​and latitude coordinate values, and the precision of the longitude coordinate values ​​and the latitude coordinate values ​​may be set to 4 decimal places. Exemplarily, the first positioning information may be expressed as (40.0302, 116.4085).

[0076] S102: Acquire second positioning information of the location of the mobile terminal.

[0077] In one implementation, the second positioning information of the location of the mobile terminal can be obtained before the target APP starts collecting on-site operation and maintenance photos. For example, the second positioning information of the location of the mobile terminal can be obtained by the target APP using the positioning function of the mobile terminal.

[0078] In one embodiment, the second positioning information may be GPS positioning information, which may adopt the WGS-84 coordinate system. The second positioning information may include longitude coordinate values ​​and latitude coordinate values, and the precision of the longitude coordinate values ​​and the latitude coordinate values ​​may be set to 4 decimal places. Exemplarily, the second positioning information may be expressed as (40.0300, 116.4084).

[0079] S103, verify whether the distance difference between the first positioning information and the second positioning information is within a preset distance threshold range. When the distance difference between the first positioning information and the second positioning information is not within the preset distance threshold range, execute step S104, or when the distance difference between the first positioning information and the second positioning information is within the preset distance threshold range, execute step S105.

[0080] In one embodiment, when the distance difference between the first positioning information and the second positioning information is not within the preset distance threshold range, it means that the distance range between the user and the ambient air quality monitoring site is not within the allowed range. At this time, step S104 is executed to not allow the user to collect operation and maintenance photos. When the distance difference between the first positioning information and the second positioning information is within the preset distance threshold range, it means that the distance range between the user and the ambient air quality monitoring site is within the allowed range. At this time, step S105 can be executed to allow the user to collect operation and maintenance photos.

[0081] In specific implementation, the preset distance threshold range can be set according to actual needs, and the embodiments of the present application are not limited to this.

[0082] S104: prohibiting the photo collection function of the target APP from being enabled.

[0083] S105, start the photo collection function of the target APP.

[0084] In one implementation, the photo collection function of the target APP may be embedded in the operation and maintenance task work order in the form of a component.

[0085] In an embodiment of the present application, by executing steps S103-S105, it is possible to ensure that the user goes to the environmental air quality monitoring site to carry out operation and maintenance and collect operation and maintenance photos before collecting photos through the target APP, and it can be ensured that the on-site operation and maintenance photos collected through the target APP are of the environmental air quality monitoring site specified in the operation and maintenance task work order, thereby avoiding human interference and falsification from the source.

[0086] S106. Collect and generate on-site operation and maintenance photos of the ambient air quality monitoring site through the target APP.

[0087] In one implementation, the implementation process of step S106 may include the following steps:

[0088] S1061. Collect on-site photos of the environmental air quality monitoring site through the target APP.

[0089] S1062. Obtain the collection time information of the on-site photo and the unique coding information and first positioning information of the ambient air quality monitoring site.

[0090] S1063: Generate the on-site operation and maintenance photo by embedding a watermark according to the on-site photo and its acquisition time information, the unique coding information and the first positioning information.

[0091] It can be understood that the on-site operation and maintenance photo contains watermark information such as the acquisition time information, the unique coding information and the first positioning information.

[0092] In the embodiment of the present application, by executing steps S1061 to S1063, it is possible to prevent the on-site operation and maintenance photos from being tampered with while facilitating the work order reviewers to quickly understand the detailed information of the on-site operation and maintenance photos.

[0093] S107. Calculate a hash value for the on-site operation and maintenance photo to obtain a first photo hash value.

[0094] In specific implementation, the existing hash calculation method can be used to calculate the hash value of the on-site operation and maintenance photos, which is not limited in the embodiments of the present application.

[0095] S108. Generate an encrypted ciphertext using an encryption algorithm according to the unique coding information and the hash value of the first photo.

[0096] In one implementation, a photo string can be constructed according to the unique coding information and the first photo hash value in the form of unique coding information + first photo hash value; and then the encryption algorithm is used to encrypt the photo string to generate the encrypted ciphertext.

[0097] For example, it is assumed that the unique encoding information and the first photo hash value are as follows:

[0098] Unique coding information: 110000001;

[0099] First photo hash value: 24254c6607d1fc21d9159f4ed4d6e505;

[0100] The constructed photo string is: 11000000124254c6607d1fc21d9159f4ed4d6e505;

[0101] Assume the encryption key is:

[0102] 5aSn5a626KaB5rOo5oSP6Lqr5L2T77yM5LiN6KaB54as5aSc5YaZ5Luj56CB;

[0103] Then encrypt the photo string and generate the encrypted ciphertext as follows:

[0104] Iju1qBo6ipCQ7Va+J3eEC9t9Zypj2yPJJ+SP1a+3bi61uSpBXh0nOvkdQTEXAI j7.

[0105] As an example, the encryption algorithm may be a DES symmetric encryption algorithm.

[0106] S109: Add the encrypted ciphertext to the attribute information of the on-site operation and maintenance photo to obtain the on-site operation and maintenance encrypted photo.

[0107] In one implementation, the encrypted ciphertext may be used as a title in the attribute information of the on-site operation and maintenance photo to obtain the on-site operation and maintenance encrypted photo.

[0108] In one implementation, the on-site operation and maintenance encrypted photo may be stored in a mobile terminal.

[0109] S110, uploading the encrypted photos of on-site operation and maintenance to the operation and maintenance platform through the target APP.

[0110] In one implementation, the photo upload function of the target APP may be embedded in the operation and maintenance task work order in the form of a component, so as to facilitate the selection and upload of photos stored in the mobile terminal.

[0111] In an embodiment of the present application, by installing the target APP in the mobile terminal (i.e., the user device), based on the unique coding information of the environmental air quality monitoring site in the operation and maintenance task work order issued by the center, the first positioning and the first photo hash value of the on-site operation and maintenance photos of the environmental air quality monitoring site, by verifying whether the distance difference between the mobile terminal and the environmental air quality monitoring site is within the preset distance threshold, and by encrypting the on-site operation and maintenance photos to generate on-site operation and maintenance encrypted photos, it is possible to prevent the mistransmission and tampering of photos on the mobile terminal (i.e., the user end), while taking into account the need for operation and maintenance personnel to carry out operation and maintenance photo collection work in an environment with poor network conditions at the environmental air quality monitoring site and temporarily store on-site operation and maintenance photos, avoid the mistransmission and tampering of photos in on-site operation and maintenance, ensure the authenticity of the traces left by the operation and maintenance work of the environmental air quality monitoring site, and effectively prevent the occurrence of human interference.

[0112] In an applicable scenario of the present application, combined with Figure 1 and Figure 2As shown, the method for preventing wrong transmission and tampering of photos provided in the embodiment of the present application may also include the following steps:

[0113] S111. Before uploading the encrypted photos of on-site operation and maintenance to the operation and maintenance platform, obtain attribute information of the encrypted photos of on-site operation and maintenance.

[0114] S112. Decrypt the encrypted ciphertext in the attribute information using a decryption algorithm to obtain a decrypted plaintext.

[0115] As an example, the encrypted ciphertext in the attribute information can be decrypted using the DES symmetric encryption algorithm to obtain the decrypted plaintext. For example, the obtained decrypted plaintext can be expressed as: 11000000124254c6607d1fc21d9159f4ed4d6e505, which is the photo string in the above example.

[0116] S113. Calculate a second photo hash value of the on-site operation and maintenance encrypted photo.

[0117] In specific implementation, the existing hash calculation method can be used to calculate the hash value of the on-site operation and maintenance encrypted photos, which is not limited in the embodiments of the present application.

[0118] In one embodiment, the second photo hash value is the same as the first photo hash value.

[0119] S114. Obtain unique coding information of the ambient air quality monitoring site, and determine the character length N of the unique coding information.

[0120] As an example, when the unique coding information of the ambient air quality monitoring site is 110000001, it can be determined that the character length N of the unique coding information is 9.

[0121] S115. Determine whether the decrypted plaintext matches the second photo hash value and the unique coding information. When it is determined that the first N characters in the decrypted plaintext match the unique coding information, and the N+1th character to the last character in the decrypted plaintext match the second photo hash value, execute step S116, or, when it is determined that the first N characters in the decrypted plaintext do not match the unique coding information, and / or, when the N+1th character to the last character in the decrypted plaintext do not match the second photo hash value, execute step S117.

[0122] In one implementation, the following two judgment processes may be performed simultaneously or in a corresponding order:

[0123] The first judgment process: match the first N characters in the decrypted plaintext with the unique encoding information to determine whether the two are consistent.

[0124] In the first judgment process, the string extraction function may be called to extract the first N characters in the decrypted plaintext as the first extracted characters, and then the first extracted characters are matched with the unique encoding information to determine whether the two are consistent.

[0125] The second judgment process: match the N+1th character to the last character in the decrypted plaintext with the hash value of the second photo to determine whether the two are consistent.

[0126] In the second judgment process, the string extraction function is called to extract the N+1th character to the last character in the decrypted plaintext as the second extracted character, and then the second extracted character is matched with the hash value of the second photo to determine whether the two are consistent.

[0127] After the above two judgment processes, when it is determined that the first N characters in the decrypted plaintext match the unique coding information, and the N+1th character to the last character in the decrypted plaintext match the hash value of the second photo, step S116 can be executed.

[0128] After the above two judgment processes, when only the first N characters in the decrypted plaintext do not match the unique coding information, it is determined that the on-site operation and maintenance encrypted photo is mistransmitted, and step S117 can be executed. In this case, the prompt information output by the target APP is used to warn that the on-site operation and maintenance encrypted photo is mistransmitted.

[0129] After the above two judgment processes, when only the N+1th character to the last character in the decrypted plaintext does not match the hash value of the second photo, it is determined that the on-site operation and maintenance encrypted photo has been tampered with, and step S117 can be executed. In this case, the prompt information output by the target APP is used to warn that the on-site operation and maintenance encrypted photo has been tampered with.

[0130] After the above two judgment processes, if it is determined that the first N characters in the decrypted plaintext do not match the unique coding information, and the N+1th character to the last character in the decrypted plaintext do not match the second photo hash value, it is determined that the on-site operation and maintenance encrypted photo is both mis-transmitted and tampered with, and step S117 can be executed. In this case, the prompt information output by the target APP is used to warn that the on-site operation and maintenance encrypted photo is mis-transmitted and tampered with.

[0131] S116. Determine that the encrypted photos of the on-site operation and maintenance are not mis-transmitted or tampered with, and upload the encrypted photos of the on-site operation and maintenance to the operation and maintenance platform through the target APP.

[0132] S117. Outputting, through the target APP, a prompt message for warning the on-site operation and maintenance staff that the encrypted photo has been mis-transmitted and / or tampered with, and generating an alarm log and uploading it to the operation and maintenance platform.

[0133] As an example, in step S117, uploading the encrypted on-site operation and maintenance photos to the operation and maintenance platform may also be prohibited.

[0134] In an embodiment of the present application, by executing steps S111-S117, the attribute information of the on-site operation and maintenance encrypted photos can be verified with the unique coding information of the environmental air quality monitoring site and the matching of the second photo hash value of the on-site operation and maintenance encrypted photos, so that when the on-site operation and maintenance photos are mistransmitted and / or tampered with on the user side, the user can be promptly prompted, further avoiding the mistransmission and tampering of photos in the on-site operation and maintenance of the environmental air quality monitoring site, ensuring the authenticity of the traces left by the operation and maintenance work of the environmental air quality monitoring site, and effectively preventing the occurrence of human interference.

[0135] In summary, the method for preventing mistransmission and tampering of photos provided in the embodiments of the present application can take into account the needs of operation and maintenance personnel to carry out operation and maintenance photo collection work in an environment with poor network conditions at the environmental air quality monitoring site, and temporarily store on-site operation and maintenance photos of the environmental air quality monitoring site. At the same time, it avoids the mistransmission and tampering of photos that exist in the on-site operation and maintenance of the environmental air quality monitoring site, ensures the authenticity of the traces left by the operation and maintenance work of the environmental air quality monitoring site, and effectively prevents the occurrence of human interference.
