In the prior art, security holes exist, community correction data can be forged through computer technology, and the security performance of correction equipment is reduced.
Therefore, the invention aims to provide a high-safety self-service correction terminal, a data processing device is additionally arranged in the self-service correction terminal, the data processing device is connected with a camera device, the data processing device is configured to encrypt video data of the camera device, and the encrypted video is locally stored; meanwhile, the data processing device is further configured to decrypt the encrypted video data, and when a data uploading event is triggered, whether the data video stored locally and to be uploaded is encrypted or not is identified; if yes, decrypting the video data stored locally, and uploading the decrypted video data and identity information based on a communication link; if not, generating the video forgery alarm information and sending out.
As shown in FIG. 1, the high-security self-help correction terminal provided by the invention comprises an identity information acquisition device, a camera device and a data processing device.
The identity information acquisition device is mainly used for identity verification, is used for acquiring identity information of a correction object, such as identity card detection, face recognition and biological fingerprint acquisition, and is used for checking the identity information and judging whether the currently acquired identity information is matched with the correction object or not. When the correction object performs operations such as reporting, learning, etc., authentication is required. The identity information acquisition device is realized by related hardware arranged on the high-security self-help correction terminal and a software program deployed on the high-security self-help correction terminal, and is common knowledge in the art, and is not described herein too much.
The image pickup device is used for recording and storing corresponding activities of the correction object to form video data when the correction object performs operations such as reporting, learning and the like. In one implementation, the camera device starts to collect video data of the target area when the high-security self-help correction terminal is awakened or the identity information collection device is awakened.
As shown in fig. 2, the data processing device is connected to an image capturing device, and the data processing device is configured to encrypt video data of the image capturing device, and includes the following encryption methods:
s100: and acquiring the video data currently acquired by the camera device and the identity information of the correction object currently acquired by the identity information acquisition device.
In one implementation, the camera device is a plurality of camera components arranged on a display screen of the self-help correction terminal, and when the correction object is subjected to operations such as reporting, learning and the like, the camera device records and forms video data of the movement of the correction object. Wherein, the data video is preferably coded by adopting H.264 or HEVC standard, or H.264/HEVC standard.
In an implementation, the camera device starts to collect video data of the target area when the high-security self-help correction terminal is awakened or the identity information collection device is awakened.
S200: encrypting the video data, and storing the encrypted video data locally in association with the identity information.
Through this design, through the inside operation of encrypting the storage of video of correcting terminal by oneself for distinguish the video that self-service correction terminal self gathered and abnormal way store the fake video at self-service correction terminal, and then can discern and correct whether the object has the condition of evading the supervision, in order to solve prior art and have the security hole, have high security.
In one implementation, the encrypting the video data specifically includes: and after entropy decoding is carried out on the video data code stream, carrying out key encryption on non-zero coefficients of the DCT coefficients of the syntax elements, and then obtaining encrypted video data after entropy encoding.
It should be noted that, entropy coding of HEVC coding standard adopts CABAC technology. The CABAC entropy coding process is divided into two steps, syntax element binarization, and binary bit stream (bins) arithmetic coding. Wherein the arithmetic coding is further divided into conventional arithmetic coding based on a context model and bypass arithmetic coding employing an approximate equal probability model.
Specifically, the present invention realizes video encryption by manipulating the sign bits of the non-zero coefficients of the syntax elements DCT coefficients after entropy decoding the video bitstream encoded by the H.264 or HEVC standard.
In CABAC entropy encoding of the present invention, the syntax element using the bypass encoding mode includes the sign bit of the non-zero coefficient after DCT-transform of the syntax element. The change of the sign bit can generate obvious perception disturbing effect on the video reconstruction collected by the self-help correction terminal, but does not have any influence on the code stream structure.
In a specific embodiment, the step of encrypting the video data in S200 specifically includes:
s210: generating a binary pseudo-random sequence by using the encryption key;
s220: and (3) entropy decoding by a CABAC technology to obtain a binary string of the original video code stream acquired by the camera device.
S230: performing bit exclusive OR operation on the binary string of the non-zero coefficient sign bit of the DCT coefficient of the syntax element to obtain an encrypted binary string;
s240: entropy coding is carried out on the binary string obtained after encryption;
s250: and repeating 230-S240 until the video code stream is finished, and obtaining the encrypted video data.
As shown in fig. 3, in a preferred implementation, the data processing apparatus is further configured to decrypt the encrypted video data, including the following decryption method:
s300: when a data upload event is triggered, it is identified whether video data stored locally and to be uploaded is encrypted.
In an example, the triggering of the data uploading event may be an active triggering of a manager, or an automatic triggering when the self-service correction terminal is idle, or an automatic triggering according to a preset period, or an automatic triggering of the data uploading event when the locally stored video meets a number threshold or a storage size threshold. And identifying encrypted video is prior art in the art and will not be described in detail herein.
S310: if yes, decrypting the video data stored locally, and uploading the decrypted video data and identity information based on a communication link.
In one implementation, the decrypting the locally stored video data specifically includes: and (3) performing entropy decoding on the encrypted video data code stream, decrypting by using a secret key, and performing entropy encoding to obtain decrypted video data.
In one implementation, the data processing device has authorization of an encryption key, decrypts the video data to be uploaded first by using the encryption key, decrypts the video data code stream to be uploaded by using the reversibility of the exclusive-or operation, and recovers the video data decrypted by the original binary string.
S320: if not, generating the video forgery alarm information and sending out.
In one implementation, the video counterfeit alarm information is sent to the mobile terminal of the guiding personnel in a short message mode, or an audible and visual alarm lamp is sent out by the self-help correction terminal, or corresponding alarm information is displayed on a display screen of the self-help correction terminal.
Through the design, when the data uploading event is triggered, the self-help correction terminal identifies whether the data video which is stored locally and to be uploaded is encrypted or not, and the encrypted video is decrypted and transmitted, so that the fake video is prevented from being transmitted to the background, and the safety is further improved.
The self-service correction terminal can encrypt and store the video, and can transmit the video after decryption to the background, and the self-service correction terminal and the video after decryption cooperate with each other to improve the security of informationized monitoring of the correction object through encryption and decryption technology.
As shown in fig. 1, in a preferred implementation, the high-security self-service correction terminal further includes a positioning device, where the positioning device is configured to collect current location information of the high-security self-service correction terminal. At present, the positioning of the correction object is mainly monitored by installing a corresponding monitoring program through a mobile phone or by wearing electronic products such as a positioning bracelet, and when the correction object enters a related mechanism to report to learning and the like, whether correction personnel are using a self-service correction terminal or not is judged by positioning, and whether the correction personnel perform the actions of masquerading and escaping from monitoring or not is judged. The method is convenient to use, but the same way, corresponding security holes exist, such as the positioning information can be forged, and when the autonomous correction terminal is moved to the side of the correction object to escape from supervision, whether the correction object reports to the study according to the specification cannot be monitored.
To this end, as shown in fig. 4, in order to further increase the security of the self-service correction terminal, the data processing device is further configured to:
s10: and acquiring the current position information of the positioning device.
In one implementation, the positioning device may be a GPS module or other software or hardware with positioning functions.
S20: and loading a pre-stored geofence, and judging whether the current position information is positioned in the geofence.
Geofencing (Geo-fencing) is a new application of LBS, namely, the use of a virtual fence to enclose a virtual geographic boundary. The geofence (namely a group of longitude and latitude coordinate pairs with closed ends) is adopted to divide the area or the street where the related organization is located, when the method is applied to community correction, the geofence of the specific area or street can be set aiming at different related organization addresses, and then whether a certain point is located in the fence can be judged rapidly and efficiently.
In one implementation, the determination may be made by a ray method, which is a horizontal scan line method or a vertical line method, to determine whether a point is within the region. If there is a location point P (x, y), it is determined whether it is within the polygon, and a horizontal scan line (i.e., ray) may be directed to the left from the question point. The number of intersections c of the line segment with the region boundary is calculated. If c is an odd number, the position point is in the polygon; even, the location point is outside the polygon.
S21: if yes, returning a hit result, and executing an encryption method to encrypt the video data based on the hit result,
s22: if not, returning a miss result, generating abnormal position alarm information based on the miss result and sending out the abnormal position alarm information.
In one specific embodiment, the abnormal position warning information is sent to the intelligent terminal of the manager in a short message mode.
Through the design, before the correction object reports to the study, the self-service correction terminal judges the position of the terminal in advance so as to eliminate the problem that the autonomous correction terminal is moved to help the correction object to escape from supervision, and further monitor whether the correction object reports to the study according to the specification; the security of informationized monitoring of the correction object is comprehensively improved through cooperation of a positioning and identification technology before video shooting and a triple technology of video encryption, storage, decryption and transmission.
As shown in fig. 5, in a preferred implementation, the data processing apparatus is further configured to:
s1000: and acquiring the current position information of the positioning device.
S2000: and carrying out AES-OFB encryption on the current position information through the embedded key to obtain a binary sequence to be embedded.
S3000: entropy decoding is performed on the encrypted video data code stream to obtain a binary string of encrypted video data.
S4000: and replacing the target position in the binary string by the binary sequence, and performing entropy coding on the binary string after replacement to obtain encrypted video data containing the current position information.
In one implementation, since information hiding is applied to encrypted video, data embedding should not affect encrypted sign bits. In one implementation, a binarized string of MVDs may also be selected as the information hiding domain. The hidden storage of the current position information in the video data can be realized by applying a binary string codeword equal-length substitution method to the MVD suffix part. Both encryption and information hiding are accomplished in CABAC bypass encoding mode, and the "current location information" tag can be embedded directly in the encrypted video.
By the design, the difficulty of video counterfeiting is further improved, and the video data is further prevented from being counterfeited, so that the safety is improved. On the other hand, when the video data is in dispute or problem, the positioning information of the video data during shooting can be obtained through reverse data extraction, whether the video is shot in the geofence of the corresponding related mechanism is judged based on the positioning information, and further whether the problem of counterfeiting the video is deduced, and evidence can be provided for the authenticity and reliability of the data video.
Specifically, the data processing apparatus has authorization of the encryption key, and decrypts the received video by using the encryption key. The decrypted video, which still contains the secret information, can further extract data for tracking the video source, which steps are as follows: decrypting the video code stream to be uploaded by utilizing the reversibility of the exclusive OR operation to obtain a decrypted video code stream containing embedded information; the operation procedure is the same as the data extraction of the encryption domain to obtain embedded information, i.e. current location information.
In a preferred implementation, the uploading of the decrypted video data and the identity information based on the communication link specifically includes:
the high-security self-service correction terminal is provided with a first quantum key machine connected with the data processing device through an intranet;
