Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with one or more embodiments of the present specification. Rather, they are merely examples of apparatus and methods consistent with certain aspects of one or more embodiments of the specification, as detailed in the claims which follow.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
Fig. 1 is a flowchart of a content validation method of a multimedia protocol according to an exemplary embodiment. As shown in fig. 1, the method applied to the blockchain node may include the following steps:
In one embodiment, the electronic device may be configured as a blockchain link point in a blockchain network by installing and running a client of the blockchain on the electronic device, for example, the electronic device may include various types such as a server, a PC, a tablet computer, a mobile phone, and the like; in other words, the block link point may be carried on any type of electronic device, and this specification does not limit this.
In one embodiment, the content of the first information may be a video clip or an audio clip of the protocol content read out by the protocol participant; or, the content of the first information may be a text printed with the protocol content or a video clip of the electronic device shown with the protocol content, which is held by the protocol participant; alternatively, the first information may characterize the protocol content in other ways, which the present specification does not limit.
In one embodiment, the content of the second message may say a statement for the protocol participant similar to "i agree", "i confirm", "i agree", or the like; alternatively, the content of the second information may be an action characterizing "approval" for the protocol participant, such as nodding the head, reaching out the thumb, smiling, etc.; alternatively, the second information may be characterized by an "approved" meaning in other ways, which the specification is not limited to.
In an embodiment, the protocol content is represented by the first information in the first multimedia data, and the approval attitude of the protocol participant to the protocol content is represented by the second information, so that the first multimedia data in the specification actually already realizes a function required to be realized by a text protocol in the related art, and the protocol participant does not need to specifically form the text content in the technical scheme of the specification, and particularly when a plurality of protocol participants are involved, the plurality of protocol participants do not need to go to the same place to sign the protocol, thereby ensuring the validity of the protocol, greatly simplifying the operation of the protocol participants, and improving the protocol signing efficiency.
In one embodiment, if there are multiple protocol participants, there may be multiple scenarios: for example, a plurality of protocol participants may use different electronic devices, and each protocol participant may collect and upload first multimedia data through the electronic device used by the protocol participant; for another example, a plurality of protocol participants may be located at the same location, and the protocol participants may share one electronic device, such as collecting and uploading the first multimedia data by the electronic device in turn, or collecting and uploading the first multimedia data by the electronic device to the protocol participants at the same time; of course, other situations are possible and this description is not intended to be limiting.
In one embodiment, the block link point may invoke an intelligent contract, which is used to verify whether the protocol content characterized by the first information is valid. For example, the block link point may analyze the protocol content represented by the first information, extract the protocol content into text information, and provide the text information to the intelligent contract, so that the intelligent contract may analyze the protocol content represented by the first information, such as whether a sensitive word is hit, whether illegal semantics are expressed, and the like, which is not limited in this specification. When the protocol content is verified to be valid, allowing the block chain node to perform other operations; when the protocol content is verified to be illegal or invalid, the first multimedia data can be judged as an invalid protocol, and an invalid mark can be added to the first multimedia data or the first multimedia data can be prevented from being effective.
And 104, calling an intelligent contract, wherein the intelligent contract is used for identifying the characteristic information contained in the protocol content represented by the first information, and outputting an additional confirmation request of the characteristic information to the protocol participant.
In one embodiment, the feature information may include: information according to predefined rules of easy misuse. For example, when a certain vocabulary has the condition of same or similar pronunciation but different expressed meanings, the vocabulary can be judged to accord with the above oral error-prone rule; for example, for some key names (such as landlord and tenant in a house renting agreement), place names (such as room address in the house renting agreement), numbers (such as rent and date) and the like, misunderstanding caused by ways of accent change, tone height and the like is avoided.
In an embodiment, a keyword library meeting the error prone rule may be predefined, and the matching keyword in the first information is determined by performing matching recognition on the first information, so as to serve as the feature information.
In an embodiment, the first information may be subjected to semantic recognition and analysis to determine information meeting the error prone rule, such as the name of the person, the name of the place, the number, and the like, as the feature information.
And step 106, acquiring second multimedia data in a video or audio form returned by the protocol participant according to the additional confirmation request, wherein the second multimedia data comprises additional confirmation information of the characteristic information.
In one embodiment, when the second multimedia data includes additional confirmation information for the characteristic information, it is equivalent to that the protocol participant confirms the characteristic information in the first information again, thereby reducing the problems of unclear and ambiguous protocol content, vulnerability and the like caused by misstatement, accent, pitch variation and the like of the protocol participant, and facilitating the maintenance of the benefit of the protocol participant.
In an embodiment, the first multimedia data and the second multimedia data may respectively employ different languages to confirm the feature information. For example, the first multimedia data may be expressed by using chinese language for the first information including the feature information, and the second multimedia data may be confirmed by using english language for the feature information. By adopting different voices to confirm the same characteristic information, the probability that the protocol content is unclear, ambiguous, vulnerable and the like due to misstatement, accent, tone change and the like of the protocol participants can be reduced, and the method is helpful for maintaining the benefits of the protocol participants.
In one embodiment, an intelligent contract may be invoked, the intelligent contract being used to verify whether the agreement participant's approval of the agreement content, as characterized by the second information, and/or the agreement participant's approval of the characteristic information, as characterized by the additional confirmation information, is valid. For example, the block link points may analyze the recognition condition respectively characterized by the second information and the additional confirmation information, and provide the recognition condition to the intelligent contract, so that the intelligent contract may analyze the recognition condition respectively characterized by the second information and the additional confirmation, such as whether the recognition condition is ambiguous or ambiguous, whether a duress condition exists, and the like, which is not limited by the present specification. When the acceptance condition is verified as valid, allowing the block link point to perform other operations; when the approval condition is verified to be illegal or invalid, the first multimedia data and the second multimedia data can be determined as invalid protocols, and invalid marks can be added to the first multimedia data and the second multimedia data or the video data can be prevented from being effective.
In one embodiment, when there are multiple protocol participants, the multiple protocol participants may correspond to the same second multimedia data, and the second multimedia data includes additional confirmation information for characterizing the approval of the multiple protocol participants for the feature information. In another embodiment, when there are a plurality of protocol participants, the plurality of protocol participants respectively correspond to different second multimedia data, and each second multimedia data includes additional confirmation information for characterizing approval of the corresponding protocol participant for the characteristic information.
In an embodiment, by publishing the first multimedia data and the second multimedia data into the blockchain, it can be ensured that the first multimedia data and the second multimedia data cannot be tampered or tampering behavior of the first multimedia data and the second multimedia data can be verified, and the first multimedia data and the second multimedia data can be traced by querying a blockchain book, which has extremely high reliability.
In an embodiment, the digital digest information of the first multimedia data and the second multimedia data may be generated separately, for example, the digital digest information may be a hash value. The digital summary information corresponding to the first multimedia data and the second multimedia data is published into the blockchain, or the digital summary information corresponding to the digital summary information of the first multimedia data and the second multimedia data is further generated and published into the blockchain, and the first multimedia data and the second multimedia data are stored locally without being linked, so that the first multimedia data and the second multimedia data cannot be tampered or tampering behaviors of the first multimedia data and the second multimedia data can be verified based on the unique matching relationship among the first multimedia data, the second multimedia data and the digital summary information, meanwhile, the content of the first multimedia data and the content of the second multimedia data can be prevented from being disclosed, and privacy protection is facilitated.
In an embodiment, the tile link point may obtain subscription attributes of the first multimedia data and the second multimedia data, for example, the subscription attributes may include at least one of the following: identity information of the protocol participants, locations of the protocol participants, a protocol signing time, and the like, which are not limited in this specification. Then, when the first multimedia data and the second multimedia data are published to the blockchain, the blockchain link point can also associate and publish the signing attribute, so that the protocol events represented by the first multimedia data and the second multimedia data have more dimensional characteristic information, which is helpful for improving the credibility of the first multimedia data and the second multimedia data.
In one embodiment, the block link point may invoke an intelligent contract, and the intelligent contract is used to verify whether the protocol contents represented by the first information included in each first multimedia data are consistent in the case that the plurality of protocol participants respectively correspond to different first multimedia data. For example, the block link points may respectively extract protocol contents represented by the first information in each first multimedia data, and transmit the protocol contents to the intelligent contract, so that the intelligent contract compares the protocol contents corresponding to each first multimedia data; if the protocol contents are all consistent, allowing the block link nodes to perform other operations, if the protocol contents are not completely consistent, judging the first multimedia data generated at this time as an invalid protocol, and adding an invalid mark to the first multimedia data or preventing the first multimedia data from taking effect (avoiding forming the multimedia protocol based on the first multimedia data).
In one embodiment, a block chain node may invoke an intelligent contract, the intelligent contract being used to generate a text protocol from the video data and signed by a data identity of the protocol participant; then, when the first multimedia data and the second multimedia data are issued to the blockchain, the blockchain node also issues the word protocol in an associated manner.
In one embodiment, the protocol in this specification may include a single protocol, such as promissory note, will, statement, etc., and this specification is not intended to be limiting. In one embodiment, the agreement in this specification may include a multi-party agreement or referred to as a contract, such as a house rental contract, a product buying and selling contract, a labor contract, and the like, which is not limited in this specification.
For convenience of understanding, the following description will be made on technical solutions of one or more embodiments of the present specification by taking an example of protocol subscription. Fig. 2 is a schematic diagram of an implementation of real person authentication according to an exemplary embodiment. As shown in fig. 2, assuming that the user a uses the mobile phone 21 (or other types of electronic devices, which is not limited in this specification), the APP client running a certain application X on the mobile phone 21 or the website corresponding to the application X may be loaded to provide the user a with the subscription function of the video protocol. In the signing process of implementing the video protocol, the application X can perform real person authentication on the user A so as to effectively manage the personal real identity of the user A and accurately define protocol participants (namely the user A) of the related video protocol.
In an embodiment, the mobile phone 21 may perform image acquisition on the user a through a camera module, so that the acquired image or video includes a face image of the user a, an image of a valid document (such as an identity card) held by the user a, an image of a corresponding action executed by the user a according to an instruction, and the like, and serves as identity data for the user a, and the mobile phone 21 uploads the identity data to the server 22, so that the server 22 may perform real person authentication on the user a based on various technical means such as face detection, face recognition, OCR document recognition, living body detection, and the like.
After the real person authentication is completed, the user a may sign a corresponding video protocol based on the authenticated identity information. Fig. 3 is a diagram illustrating an exemplary embodiment of a subscription to a multimedia protocol. As shown in fig. 3, the mobile phone 21 may perform multimedia data acquisition on the user a, for example, perform video acquisition through a camera, perform audio acquisition through a microphone, or perform audio and video acquisition simultaneously, and ensure that the acquired multimedia data can at least represent contents in two aspects: on the one hand, the multimedia data need to characterize the contents of the agreement to be signed, and on the other hand, the multimedia data need to characterize the approval of the contents of the agreement by the user a.
The user a can form multimedia data satisfying the above requirements in various ways. For example, the user a may speak the voice content satisfying the above requirements while facing the lens of the cellular phone 21; for another example, when facing the lens of the mobile phone 21, the user a may also display the electronic device printed with the text or displayed with the content meeting the above requirements in front of the lens; as another example, user A may take multiple forms as described above simultaneously.
For example, when the user a speaks a voice content such as "i promise to donate 100 ten thousand renminbi to XX organization" in the face of the shot of the mobile phone 21, the represented agreement content may be "the user a donates 100 ten thousand renminbi to XX organization", and the sentence pattern of "i promise … …" expresses the approval attitude of the user a to the agreement content, and thus may be considered to meet the above requirements. For another example, when facing the shot of the mobile phone 21, the user a may present paper printed with "i promise to donate 100 ten thousand renminbi to the XX organization" before the shot, which also meets the above requirements. For another example, when facing the shot of the mobile phone 21, the user a may present paper printed with "donate 100 ten thousand renminbi to XX organization" in front of the shot, and speak the voice content such as "i approve the protocol content currently shot", which also satisfies the above requirements.
The above embodiments relate to the user a signing into a single multimedia protocol, i.e. the protocol participants of the multimedia protocol only comprise the user a, but this scenario does not mean that only the user a can be present in the multimedia data. For example, as shown in fig. 4, both the user a and the user B may be present in the multimedia data collected by the mobile phone 21, and the server 22 may perform real person authentication for the user a and the user B respectively; after the real person authentication is passed, the user B may assist the user a to complete the multimedia collection, for example, the user B dictates the agreement content, and the user a confirms the agreement content dictated by the user B, for example, the dictation of the user B may be "100 ten thousand renminbi donated by the user a to XX organization", and the user a may confirm the agreement content such as "i agree".
In one embodiment, the server 22 can analyze the multimedia data uploaded by the handset 21 to determine the multimedia content contained therein, such as the above-mentioned protocol content, the approval of the protocol content by the user a, and the like. Then, the server 22 may invoke the intelligent contract to check the multimedia content based on the check rule defined in the intelligent contract; wherein the verification rule may comprise at least one of: whether the protocol content includes illegal content (for example, whether the protocol content includes preset sensitive words or not may be matched), whether the protocol content includes invalid content (for example, whether the protocol content is clear and accurate through semantic analysis), whether the protocol participant approves the protocol content (for example, whether the protocol participant sends out a voice expressing "approval" or makes an action expressing "approval"), whether the state of the protocol participant expressing "approval" is normal (for example, whether the intonation or expression of the protocol participant is normal, whether a situation of being stressed by a person exists, and the like), and the like, which are not limited in this specification.
FIG. 5 is a schematic diagram of an anti-misstatement process provided by an exemplary embodiment. As shown in fig. 5, for a single-party multimedia protocol signed by the user a, after receiving the multimedia data uploaded by the mobile phone 21, the server 22 may extract protocol content included in the multimedia data; server 22 may then invoke the intelligent contract to provide the extracted protocol content to the intelligent contract to verify by the intelligent contract whether the protocol content includes misleading content.
In an embodiment, the intelligent contract is predefined with an identification logic of the content prone to misstatement, for example, the protocol content is matched with predefined keywords prone to misstatement, and then, for example, specific types of information such as names, address information, and numbers identified in the protocol content are used as the content prone to misstatement, and for example, the content with unclear meaning due to the accent, pitch change, and the like of the protocol participants in the protocol content is used as the content prone to misstatement, which is not limited in this specification.
For the identified content prone to error, the smart contract may instruct the server 22 to return a corresponding content prone to error confirmation prompt to the mobile phone 21. Accordingly, the mobile phone 21 can guide the user to repeatedly confirm the content prone to error so as to acquire corresponding multimedia confirmation data. For example, assuming that the agreement content is "i promise to rent XX cell No. 2 building 302 room from user a, the rent is 3000 dollars per month", the mishapable content is "3000 dollars" expressed in chinese (e.g., by accent, pitch change, etc., which may be misinterpreted as "4000 dollars"), user a may be guided to express "Three times and yuan" in, for example, english (or other languages), thereby confirming the amount of the rent in two different languages, greatly reducing possible disputes of the amount of the rent.
Accordingly, the mobile phone 21 may upload the collected multimedia confirmation data to the server 22, and the server 22 invokes an intelligent contract to check the data content included in the multimedia confirmation data. For example, the intelligent contract may perform validity detection on data content contained in the multimedia confirmation data (such as whether sensitive words are contained or not); as another example, the smart contract may compare the data content contained in the multimedia validation data with the protocol content contained in the multimedia data to determine whether the two are consistent.
After confirming that there is no error, the server 22 may issue the corresponding multimedia protocol into the blockchain. For example, the server 22 may issue a transaction to the blockchain, where the transaction includes the multimedia data uploaded by the mobile phone 21 in fig. 3 to 4 and the multimedia confirmation data uploaded by the mobile phone 21 in fig. 6, the multimedia data and the multimedia confirmation data are signed by a key for characterizing the digital identity of the user a, so as to indicate that the multimedia data and the multimedia confirmation data are the multimedia protocol in which the user a participates, and the content of the transaction may be recorded in the blockchain ledger, so as to achieve the deposit of the multimedia protocol. Of course, the server 22 may only locally store the multimedia data and the multimedia confirmation data, and the transaction issued to the blockchain only includes the hash value of the multimedia data and the multimedia confirmation data, so on one hand, the content of the multimedia protocol may be prevented from being disclosed, which is beneficial to improving data privacy, and on the other hand, the multimedia data and the multimedia confirmation data locally stored by the server 22 may be verified according to the hash value recorded in the blockchain ledger, so as to prevent the multimedia data and the multimedia confirmation data from being tampered.
In the above embodiment, the multimedia protocol only has a single protocol participant, that is, the multimedia protocol is a single-side multimedia protocol; in other embodiments, the multimedia protocol may also be a multi-party multimedia protocol, i.e. there are multiple protocol participants, as described below for the scenario of a multi-party multimedia protocol.
It is assumed that both user a and user B are protocol participants, i.e. user a and user B participate together in signing a multimedia protocol. As shown in fig. 4, the user a and the user B may be located at the same location, and use the mobile phone 21 together to complete operations such as real person authentication and multimedia data collection. In the real person authentication process, the mobile phone 21 may simultaneously acquire images including the user a and the user B through the camera module, and accordingly perform real person authentication for the user a and the user B, which is similar to the embodiment shown in fig. 2 and will not be described here again. Or, the user a and the user B may perform time division multiplexing on the mobile phone 21, for example, the user a uses the mobile phone 21 to complete the real person authentication first, and then the user B uses the mobile phone 21 to complete the real person authentication, and the real person authentication process for each user is respectively similar to the embodiment shown in fig. 2, and is not described here again.
Then, the mobile phone 21 may perform multimedia collection on the user a and the user B to obtain corresponding multimedia data. In one embodiment, the handset 21 may generate a multimedia data comprising: the multimedia content of the protocol content required to be signed is represented, and the multimedia content of the protocol content is approved by the representation user A and the representation user B; for example, user a may (facing the shot of the mobile phone 21) say "i promise to rent XX cell 2 building 302 room to user B with a rent of 3000 yen per month", and user B may (facing the shot of the mobile phone 21) say "i promise to rent XX cell 2 building 302 room from user a with a rent of 3000 yen per month", then the agreement content is "user a rents XX cell 2 building 302 room to user B with a rent of 3000 yen per month", and the sentence pattern of user a, user B about "i promise … …" expresses the recognition attitude for the agreement content; for another example, user a or user B may present a piece of paper printed with "user a rents XX cell 2 building 302 room with 3000 dollars per month to user B" before the shot, and user a and user B may respectively speak voice content such as "i approve the currently photographed agreement content". Of course, the expression form of the multimedia content is not limited as long as the meaning of the above two aspects can be characterized.
It should be noted that: when the mobile phone 21 generates only one piece of multimedia data, the user a and the user B may complete the collection of the multimedia data at the same time, or complete the collection separately and sequentially, which is not limited in this specification.
In another embodiment, the handset 21 may generate one piece of multimedia data for the user a and the user B, respectively, where the multimedia data corresponding to the user a includes: the multimedia data corresponding to user B comprises the following multimedia contents which represent the protocol contents required to be signed and the multimedia contents which represent the approval of the protocol contents by user A: multimedia content for representing the required signed protocol content and multimedia content for representing the approval of the protocol content by the user B. For each multimedia data, the generation manner is similar to the embodiment shown in fig. 3 or fig. 4, and is not described here again.
When only one piece of multimedia data is generated by the multi-party multimedia protocol in which the user a and the user B participate, the server 22 may return an easy-to-misuse content confirmation prompt to the mobile phone 21 through an embodiment similar to that shown in fig. 5, so that the mobile phone 21 guides the user a and the user B to repeatedly confirm the easy-to-misuse content in the protocol content. Then, the server 22 obtains the multimedia confirmation data uploaded by the mobile phone 21, invokes an intelligent contract to check the data content included in the multimedia confirmation data, and issues the multimedia data and the multimedia confirmation data respectively uploaded by the mobile phone 21 to the block chain and records the multimedia data and the multimedia confirmation data as corresponding multimedia protocols. Here, reference may be made to the embodiment shown in fig. 5, but the operation of confirming the content susceptible to error only needs to be completed by the user a and the user B, and details are not described here.
Besides sharing the mobile phone 21, the user a and the user B may use different electronic devices respectively, for example, as shown in fig. 6, the user a may use the mobile phone 21, the user B may use the mobile phone 23, and especially when the user a and the user B are located at different geographical locations respectively, the multimedia protocol may still be remotely signed, and there is no need to go to the same location for signing the protocol.
In an embodiment, any protocol participant can request the server 22 for the subscription function of the multimedia protocol through the mobile phone 21, for example, when the any protocol participant is the user a, the user a can designate the user B as an associated protocol participant, so that cooperation can be realized between the mobile phone 21 (registered with the account of the user a) used by the user a and the mobile phone 23 (registered with the account of the user B) used by the user B, thereby participating in the subscription process of the same multimedia protocol together.
The mobile phone 21 may implement real person authentication for the user a and collect multimedia data related to the user a, which is similar to the case of the embodiment shown in fig. 3-4 and is not described herein again; the mobile phone 23 may perform real person authentication for the user B and collect multimedia data related to the user B, which is similar to the implementation process of the mobile phone 21 and will not be described herein again.
After the mobile phone 21 or the mobile phone 23 uploads the multimedia data to the server 22, similar to the embodiment shown in fig. 3, the server 22 may analyze the multimedia data, and then check the analysis result by invoking an intelligent contract, for example, at least one of the following aspects may be checked: whether the protocol content includes illegal content, whether the protocol content includes invalid content, whether the protocol participant approves the protocol content, whether the state of the protocol participant expressing "approval" is normal, etc., and details are not described herein.
FIG. 7 is a schematic diagram of another anti-misstatement provided by an exemplary embodiment. As shown in fig. 7, the server 22 may invoke an intelligent contract to detect the protocol content included in the multimedia data 1 uploaded by the mobile phone 21 and the protocol content included in the multimedia data 2 uploaded by the mobile phone 23, respectively, determine the content easy to misuse included in the protocol content, and send the content easy to misuse confirmation prompt 1 and the content easy to misuse confirmation prompt 2 to the mobile phone 21 and the mobile phone 23, respectively, so that the mobile phone 21 and the mobile phone 23 respectively guide the user a and the user B to repeatedly confirm the content easy to misuse in the protocol content. Then, the server 22 obtains the multimedia confirmation data 1 and the multimedia confirmation data 2 uploaded by the mobile phone 21 and the mobile phone 23, respectively, and invokes an intelligent contract to check the data content included in the multimedia confirmation data 1 and the multimedia confirmation data 2, respectively. For the anti-misstatement processing performed by the user a and the user B, reference may be made to the embodiment shown in fig. 5, which is not described herein again.
In an embodiment, since the user a and the user B may be located at different geographical locations, so that the two may not be able to directly know the multimedia collection condition of the other party, the server 22 may transmit the multimedia data or the multimedia confirmation data of one party to the other party for viewing after obtaining the multimedia data or the multimedia confirmation data of the other party. For example, a video window corresponding to each protocol participant can be displayed on the electronic device used by each protocol participant, so as to display video pictures taken by the electronic device used by each protocol participant; for example, two video windows may be displayed on the mobile phone 21 and the mobile phone 23 respectively to display the video images shot by the mobile phone 21 and the mobile phone 23 respectively, so that the user a and the user B can view the video shooting situation of the users themselves and the video shooting situation of the other users. Particularly, by mutually transmitting the multimedia data and the multimedia confirmation data, each protocol participant can acquire the multimedia data and the multimedia confirmation data of each protocol participant, so that the protocol content contained in the multimedia data and the data content contained in the multimedia confirmation data are checked, and the situations of word traps, ambiguities, errors in mouth and the like which are possibly not easy to be perceived by the server 22 are conveniently found; moreover, each protocol participant can have the authority of terminating the subscription, so that when any protocol participant disagrees with the multimedia data or multimedia confirmation data of other protocol participants and the other protocol participants refuse to modify, the protocol subscription can be terminated, and the rights and interests of the protocol participants are guaranteed.
Then, the server 22 may issue the multimedia data 1 and the multimedia confirmation data 1 uploaded by the mobile phone 21, and the multimedia data 2 and the multimedia confirmation data 2 uploaded by the mobile phone 23, to the blockchain, so as to record the multimedia protocol signed between the user a and the user B. Alternatively, four hash values (or one hash value calculated again from the four hash values) corresponding to the multimedia data 1, the multimedia confirmation data 1, the multimedia data 2, and the multimedia confirmation data 2 may be issued to the blockchain, and the multimedia data 1, the multimedia confirmation data 1, the multimedia data 2, and the multimedia confirmation data 2 are stored at the server 22 and uplink is avoided, which is helpful for implementing privacy protection.
It should be noted that: although the foregoing embodiment is described by taking an example of an agreement signing scenario between the user a and the user B when a multi-party agreement is involved, the technical solution of the present specification may also be applied between a greater number of agreement participants to implement agreement signing of three or more parties, and the present specification does not limit this.
