Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to the method for binding the information and the data evidence, the terminal device is communicated with the server or the information platform through the network. The terminal device may be, but is not limited to, various recorders, audio recorders, video recorders, and portable wearable devices. The server may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers.
In one embodiment, as shown in fig. 1, a method for binding information and data evidence is provided, which includes the following steps:
s1: and acquiring an information notification corresponding to the identity according to the identity.
Firstly, the terminal device obtains an identity, which may be a name, an identification number, etc., and then uploads the identity to the terminal device. And acquiring an information notification corresponding to the identity from the information platform according to the identity.
In a specific embodiment, as shown in fig. 2, in the step of obtaining the information notification corresponding to the identity identifier according to the identity identifier, the step includes:
s101: generating a unique subscription number according to a preset rule, and subscribing to MQTT service;
s102: and acquiring the information notification which is pushed by an information platform and corresponds to the unique subscription number through the MQTT service.
MQTT (Message queue Telemetry Transport) is a "lightweight" communication protocol based on publish/subscribe (publish/subscribe) mode, which is built on TCP/IP protocol. The MQTT has the greatest advantage that a real-time reliable message service can be provided for connecting remote devices with few codes and limited bandwidth. As an instant messaging protocol with low cost and low bandwidth occupation, the method has wide application in the aspects of Internet of things, small-sized equipment, mobile application and the like.
MQTT is a client-server based message publish/subscribe transport protocol. The MQTT protocol is lightweight, simple, open, and easy to implement, and these features make it very widely applicable, including in environments where machine or network resources are limited, such as: machine to machine (M2M) communication and internet of things (IoT). It has found widespread use in communication sensors via satellite links, occasionally dial-up medical devices, smart homes, and some miniaturized devices.
First, as shown in fig. 4, a terminal device or an information platform generates a unique subscription number for subscribing information notifications in the MQTT system according to a preset rule, where the preset rule may be obtained by computing an identity identifier such as a name and an identity card number, or may be randomly generated as long as it is ensured that each terminal is dedicated to a unique subscription number, and then the terminal device receives a push from the MQTT service according to the unique subscription number. At this time, the terminal device is the client and the information platform is the server, specifically, new information and the unique subscription number are published to the MQTT service, and on the other hand, the terminal device monitors an information notification corresponding to the unique subscription number sent by the MQTT service by subscribing to the erected MQTT service.
In a specific embodiment, as shown in fig. 3, in the step of obtaining the information notification corresponding to the identity identifier according to the identity identifier, the step includes:
s111: installing a third party application, wherein the third party application is connected to an information platform and receives the information notification;
s112: receiving the information notification received by the third party application from the information platform.
Specifically, the terminal can install a customized third-party application, and then the third-party application receives information notification from the information platform through a network interface of the third-party application. The third-party application and the information platform can be automatically developed and maintained, and the third-party application is installed through the terminal, so that the universality of the terminal can be enhanced, and the beneficial effects of reducing the purchasing threshold and the like are achieved. And after receiving the information notification from the information platform, the third-party application pushes the information notification to an interface of a terminal system, so that the terminal can receive and process the information notification from the information platform.
In a specific embodiment, as shown in fig. 2, in the step of obtaining, according to the identity, the information notification corresponding to the identity, the method further includes:
s121: scanning a two-dimensional code containing the information notice;
s122: the information notice is decoded from the two-dimensional code and is used for marking the data segment to be collected or the data segment collected in advance.
Specifically, the information notification may be sent to a collection device such as a recorder through a two-dimensional code, so as to notify the recorder to mark a data segment collected in advance or to be collected, and to be bound with the information notification. Further, after receiving the pushed information notification from the MQTT service, the terminal generates a two-dimensional code by using a zxing plug-in, and the recorder can scan the two-dimensional code through a camera thereof, and analyze and acquire the information notification from the two-dimensional code, and then use the information notification for subsequent marking on a data segment to be acquired or a data segment acquired in advance. The step of acquiring the information notification by scanning the two-dimensional code can prevent information leakage, that is, information included in the information notification is not displayed or only partial information is displayed on the terminal, but the information included in the information notification is directly acquired by the recorder, thereby further improving safety.
In a specific embodiment, in the step of obtaining, according to the identity, the information notification corresponding to the identity, the method further includes:
s131: the information notification is obtained by a wireless transmission means, and the information notification is used for marking the data segment to be collected and/or the data segment collected in advance, wherein the wireless transmission means comprises NFC communication using an HCE mode.
Specifically, the information notification may also be sent to a collecting device such as a recorder through a wireless transmission means to notify the recorder to mark the data segments collected in advance or to be collected, and to be bound with the information notification. By the wireless transmission method, information leakage can be prevented, namely, information included in the information notification is not displayed or only partial information is displayed on the terminal, but the information included in the information notification is directly acquired by the recorder, so that the safety is further improved.
More specifically, the wireless transmission means is NFC communication using the HCE mode.
HCE (host-based card emulation), a host-based card emulation.
Card simulation is realized on a mobile phone with an NFC function, and at present, two modes exist: one is hardware-based, called Virtual card mode (Virtual card mode); one is software-based, called Host Card Mode.
In the virtual card mode, a security module SE (secure element) is provided, and the SE provides secure storage of sensitive information and a secure execution environment for transaction transactions. In the host card mode, the SE is not required to be provided, but an application running in the mobile phone or a cloud server completes the SE function, and at the moment, data received by the NFC chip is sent to the application in the mobile phone or the cloud server through the operating system or the mobile network to complete interaction. Both approaches feature the limitation of bypassing the built-in SE of the handset.
Specifically, the simulation is performed through an NFC module on the mobile phone, then the interaction is performed with an NFC module of acquisition equipment such as a recorder, and data communication is performed through near field communication.
S2: when the currently collected data segment or the data segment which is collected in advance and is in the display state is not marked, the obtained information notification is marked in the currently collected data segment or the data segment which is collected in advance and is in the display state.
When the currently collected data segment or the data segment collected in advance and in the display state is not marked, the obtained data segments of audio, video and the like can be bound in two ways: (1) before the data fragment starts to be collected, the obtained corresponding information is informed to be bound in the currently collected data fragment; (2) the acquired corresponding information notification may be bound in the previously acquired data fragment after the data fragment is acquired for a certain period of time. It should be noted that the data segments described herein may be generated or intercepted as a single file, or may be marked in an entire complete audio or video file, for example, by adding marking nodes/anchor points, adding watermarks or annotations to the video file, and so on.
S3: and when the currently collected data segment or the data segment which is collected in advance and is in the display state is marked, intercepting the data segment marked with the information notice.
Specifically, after the information is acquired, it is first determined whether the existing data segment has been marked, and if the currently acquired data segment or the data segment that has been acquired in advance and is in the display state has been marked, the acquisition and information notification is skipped to the already bound segment according to the marked information notification. By this means already bound data segments can be replayed quickly, for example data segments that have been collected before playback is required when they have not been extracted from the recorder, two-dimensional codes comprising information notifications can be rescanned or information notifications can be sent again by wireless transmission means, and already bound data segments can be retrieved/jumped to quickly.
In a specific embodiment, the step of intercepting the data segment marked with the information notification further includes:
s301: segmenting the data segments into individual segment files;
s302: and naming the fragment file according to a preset naming rule, wherein the preset naming rule comprises one or more of the identity identification, the number of the information notice and the occurrence time of the information.
For convenience of archiving, separate clip files, such as separate video files, audio files, etc., may be generated directly while intercepting the data clip marked with the informational notification. Specifically, a separate video file and audio file may be directly created when the information notification is obtained, or a data segment marked with the information notification may be intercepted from a whole segment of the complete video file and audio file to generate an independent video file and audio file. Further, the intercepted independent video file and audio file can be named according to a preset naming rule, specifically, the preset naming rule comprises one or more of an identity, a number of an information notification and occurrence time of information, and can be selected as required.
S4: and displaying the acquired or intercepted data segment.
And finally, playing back the acquired or intercepted data segment on a display device of the terminal or the recorder.
In a specific embodiment, as shown in fig. 5, after the step of displaying the collected or intercepted data segment, the method further includes:
s401: receiving an input inquiry request of any one information notice;
s402: searching the corresponding data segment according to the corresponding relation between the marked information notice and the data segment;
s403: and extracting and displaying the corresponding data segment.
Specifically, the terminal and the recorder also have a function of querying a data segment corresponding to the information notification according to an input query request of the information notification. Firstly, an inquiry request of any input information notification is received, wherein the inquiry request can comprise one or more items of identification, number of the information notification and occurrence time of the information notification, and can be selected as required, and can be directly locked to a single information notification, or a batch of information notifications meeting conditions, for example, one or more information notifications corresponding to a certain period of time and the like. And then, searching the corresponding data segment according to the corresponding relation between the labeled information notice and the data segment, and finally, extracting and implementing the data segment corresponding to the query request of the input information notice.
The invention has the following technical effects: the method can convert the information notice received from the information platform into the interactive information such as the two-dimensional code, and then sends the interactive information to the acquisition equipment such as the recorder, so that the acquisition equipment can mark the data evidence acquired after the interactive information is received and bind the data evidence with the received information notice. In addition, in the technical scheme of the invention, the interactive information is sent to the recorder through the two-dimensional code or NFC, so that information leakage is avoided, and the safety and privacy of data are further ensured.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
