Fig. 2 is a flowchart for exemplarily explaining how the first embodiment implements an image data management method.
[ detailed description ] of the invention
Before the present invention is described in detail, it should be noted that: unless otherwise defined, the term "electrical connection" as used herein refers broadly to a "wired electrical connection" in which a plurality of electronic devices/apparatuses/components are connected to each other via conductive materials, and a "radio connection" in which a single/double wireless signal transmission is performed via wireless communication technology. In addition, unless otherwise specified, the term "electrically connected" as used herein refers to "direct electrical connection" formed by directly connecting a plurality of electronic devices/apparatuses/components to each other, and "indirect electrical connection" formed by indirectly connecting a plurality of electronic devices/apparatuses/components to each other through other electronic devices/apparatuses/components.
Referring to fig. 1, a first embodiment of the image data management system 1 of the present invention includes a management server 11, and the management server 11 is implemented as a single server in this embodiment. However, in other embodiments, the management server 11 may be, for example, a plurality of servers electrically connected to each other. It should be understood that the actual implementation of the management server 11 can be freely adjusted according to the requirements of cost, performance or management, and thus, the implementation of the management server 11 is not limited to the embodiment.
The management server 11 is suitable for electrically connecting a plurality of electronic devices 12 via a network (e.g., the internet), for example. Also, for convenience of description, the present embodiment is explained below with three electronic devices 12 shown in fig. 1.
In the application of the present embodiment, the three electronic devices 12 may be respectively assigned to a first party, a second party and a witness party in a traffic accident, for example. The first party may be, for example, driving one of the vehicles in the traffic accident, the second party may be, for example, driving another of the vehicles in the traffic accident, and the witness may be, for example, a witness (for example, passerby or a peer of the first party) in the traffic accident, but not limited thereto. Moreover, each of the electronic devices 12 in the present embodiment may be, for example, one of a desktop computer, a notebook computer, a tablet computer and a smart phone, but not limited thereto.
With reference to fig. 2, the following describes in detail how the image data management system 1 of the present embodiment implements an image data management method.
First, in step S1, when the management server 11 receives a blockchain network establishment request from one of the electronic devices 12 (e.g., an electronic device 12' shown in fig. 1), the management server 11 establishes a blockchain network N implemented by using a distributed ledger technique (Distributed ledger Technology, abbreviated as DLT) according to the blockchain network establishment request, and, as shown in fig. 1, the three electronic devices 12 are respectively used as at least three nodes (nodes) included in the blockchain network N, for example. Further, in a further implementation aspect of the present embodiment, the management server 11 may be, for example, one of the nodes in the blockchain network N, and optionally be used as a supernode (supernode) in the blockchain network N, but not limited thereto.
It is added that the management server 11 establishes the blockchain network N with the electronic devices 12 as nodes, for example, it is equivalent to adding the electronic devices 12 to the image data management system 1, that is, making the electronic devices 12 included in the image data management system 1.
After the management server 11 establishes the blockchain network N, the flow proceeds to step S2.
In step S2, when the management server 11 receives an encrypted image data containing a dynamic image and a decryption key corresponding to the image data, the management server 11 decrypts the image data, for example, with the decryption key, and stores the decryption key in itself.
More specifically, the image data and the decryption key may be included in an image data upload request indicating the blockchain network N, and the image data upload request may be generated by one of the electronic devices 12 or another electronic device not shown in the drawings and transmitted to the management server 11, in other words, in the present embodiment, the management server 11 obtains the image data and the decryption key by receiving the image data upload request, for example, but not limited thereto.
Further, the dynamic image is, for example, a film generated by recording a video by an image recording device (not shown), and the image recording device is, for example, a drive recorder adapted to be installed in a vehicle. Moreover, in the application of the present embodiment, the dynamic image may, for example, represent the occurrence process of the traffic accident, and is suitable to be used as a digital evidence for clearing the accident responsibility of both parties. In another aspect, the decryption key may be, for example, a public key of a key pair stored by the image recording device, and a private key of the key pair corresponding to the public key is, for example, used by the image recording device to encrypt the image data. It should be noted that the image data may further include, for example, a capturing time corresponding to the moving image and device identification data of the image recording device, but is not limited thereto.
After the management server 11 receives the image data and decrypts the image data, the flow proceeds to step S3.
In step S3, the management server 11 uploads the dynamic image to the blockchain network N for storage, i.e. at least a plurality of copies of the dynamic image are respectively established in the electronic devices 12 serving as nodes.
In this embodiment, in order to enable the electronic devices 12 to store the copy of the dynamic image and also to consider the confidentiality of the dynamic image, the management server 11 may upload the dynamic image data that is not decrypted to the blockchain network N for storage, or the management server 11 may encrypt the dynamic image first and then upload the encrypted dynamic image to the blockchain network N for storage, so that even if the electronic devices 12 store the copy of the dynamic image, the electronic devices 12 cannot access the copy of the dynamic image stored in themselves.
After the management server 11 uploads the dynamic image to the blockchain network N for storage, the flow proceeds to at least one of step S4 and step S5.
In step S4, when the management server 11 receives a browse request from a client 5 (shown in fig. 1 for example) and indicates the image data, and determines that the browse request meets a browse right condition, the management server 11 grants the browse request, obtains the dynamic image from the blockchain network N, and provides the dynamic image to the client 5 for output in an online playing manner.
In more detail, in the present embodiment, the user terminal 5 may be, for example, one of a desktop computer, a notebook computer, a tablet computer and a smart phone, and the browsing permission condition represents that the browsing request includes the public key, but is not limited thereto. In addition, in the present embodiment, when the browsing request is granted, the management server 11 transmits the dynamic image to the user terminal 5 through a network, for example, in the form of streaming media, so that the user terminal 5 can output the dynamic image in an online playing manner through, for example, a browser or a specific application. In other words, even if the management server 11 grants the browse request, the whole dynamic image is not directly provided to the ue 5 for storage, so the ue 5 does not obtain a complete copy of the dynamic image due to the browse request being granted, and certainly cannot share or edit the dynamic image further.
Further, after the management server 11 provides the dynamic image to the user terminal 5 for outputting in an online playing manner, the management server 11 generates a browse request processing record corresponding to the browse request and the dynamic image, and stores the browse request processing record in the blockchain network N. In this embodiment, the browse request processing record may include, for example, the time when the management server 11 receives the browse request, a device identification data corresponding to the ue 5, whether the browse request is granted by the management server 11, and the start time and end time when the dynamic image is provided to the ue 5 for output, but not limited thereto. The device identification data corresponding to the ue 5 may be implemented as, for example, an IP location, a MAC address, an IMEI code, or an IMSI code of the ue 5, but not limited thereto.
It is added that, in a further implementation aspect of the present embodiment, the browsing permission condition may further represent, for example, that a user account of the user terminal 5 for logging into the management server 11 is an authenticated police account. In other words, in the application of the present embodiment, the dynamic image stored in the blockchain network N can be only browsed by the principal of the traffic accident and the family thereof or the inspector of the police unit, but is not limited thereto.
In step S5, when the management server 11 receives a download request from the client 5 and indicates the image data, and also determines that the download request meets a download authority condition, the management server 11 grants the download request, obtains the dynamic image from the blockchain network N, and transmits the dynamic image to the client 5 completely.
In more detail, in the present embodiment, the download authority condition represents that a payment procedure corresponding to the download request has been completed and the download request includes the public key, but is not limited thereto. In this embodiment, in the case where the download request is granted, the management server 11 may, for example, embed a visual tag into the dynamic image, and then completely transmit the dynamic image embedded with the visual tag to the client 5. The visual mark may be implemented as a watermark that is permanently displayed on the background of the dynamic image and cannot be removed, but is not limited thereto. In other words, if the download request is granted by the management server 11, the client 5 can obtain the complete file of the moving image embedded with the visual marker, so that the client 5 can play the moving image repeatedly without network connection.
Further, after the management server 11 completely transmits the dynamic image to the ue 5, the management server 11 generates a download request processing record corresponding to the download request and to the dynamic image, and stores the download request processing record in the blockchain network N. In this embodiment, the download request processing record may include, for example, the time when the management server 11 receives the download request, the device identification data corresponding to the client 5, whether the download request is granted by the management server 11, and the start time and the end time when the moving image is completely transmitted to the client 5, but not limited thereto.
It should be noted that, in the application of the present embodiment, the dynamic image stored in the blockchain network N may be downloaded and stored only by the principal of the traffic accident and the family members thereof or the inspector of the police unit, but is not limited thereto.
The above is an example of how the image data management system 1 of the first embodiment implements the image data management method.
It should be understood that the flowcharts of steps S1 to S5 and fig. 2 in this embodiment are only for illustrating one possible implementation of the image data management method of the present invention. It should be understood that, even if the steps S1 to S5 are combined, split or sequentially adjusted, if the processes after the combination, split or sequentially adjusted achieve substantially the same effects in substantially the same manner as the present embodiment, the image data management method still belongs to the practical aspects of the present invention, and therefore, the flowcharts of the steps S1 to S5 and fig. 2 in the present embodiment are not used to limit the practical scope of the present invention.
The invention also provides a second embodiment of the image data management system 1.
In the second embodiment, the three electronic devices 12 in fig. 1 are, for example, three image recording devices, more specifically, the three image recording devices are, for example, respectively assigned to a first party, a second party and a witness party in a traffic accident, and the three image recording devices are, for example, respectively disposed on vehicles of the first party, the second party and the witness party.
In the image data management method implemented by the image data management system 1 of the second embodiment, before step S1, when a car accident occurs in the vicinity of the vehicles of the first party and the second party, one of the three image recording devices (for example, the image recording device of the first party and, for example, the electronic device 12 'in fig. 1) can determine that the car accident occurs by using, for example, image recognition or keyword recognition, and then start file-locking recording to generate image data, generate and transmit the blockchain network establishment request to the management server 11, and control the other two image recording devices adjacent to itself (for example, the two image recording devices of the second party and the witness party, respectively, that is, the other two electronic devices 12 in fig. 1 except the electronic device 12') to start file-locking recording together to generate the other two image data.
Next, in step S1 of the image data management method according to the second embodiment, when the management server 11 receives the blockchain network establishment request, the management server 11 establishes the blockchain network N with the three image recording devices as three nodes, respectively. Then, the management server 11 receives three dynamic images from the three image recording devices respectively in step S2, and uploads the three dynamic images to the blockchain network N for storage in step S3, that is, creates copies of the three dynamic images in each image recording device serving as a node, wherein the three dynamic images are generated by video recording by the three image recording devices respectively.
In the second embodiment, during the process of uploading the dynamic images to the blockchain network N by the management server 11 (i.e. during the process of establishing the copy of the dynamic image by each electronic device 12), the management server 11 and the image recording devices perform verification and comparison on the dynamic image for example, every first time length, so as to ensure that the copy of the dynamic image stored by each image recording device and the dynamic image stored by the management server 11 match each other quickly, wherein the first time length can be implemented for example, but not limited to, one minute. After the management server 11 finishes uploading the moving image, the management server 11 and the image recording devices perform verification comparison on the moving image, for example, every second time length, so as to ensure that the state of the copy stored by each image recording device is unchanged, where the management server 11 may, for example, compare a header file (header file) of the moving image stored by itself with a header file (header file) of the copy stored by each image recording device, thereby determining whether the copy stored by each image recording device is changed, and the second time length is longer than the first time length, for example, and may be implemented for twenty-four hours, thereby reducing the verification load of the management server 11 and the image recording devices, but is not limited thereto.
In summary, by implementing the image data management method, the image data management system 1 can achieve proper management of the image data by using the blockchain technology, thereby reducing the risk of intentional dissemination and falsification of the dynamic image, and effectively improving the credibility of the dynamic image as digital evidence, so as to achieve the aim of the invention.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
