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 only a part of the embodiments of the present invention, and not all of the embodiments. 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.
Fig. 1 is a schematic diagram of a performance evaluation system according to an embodiment of the present invention. As shown in fig. 1, the performance evaluation system may be composed of a cloud database, an evaluation management platform, and a plurality of terminal devices. The evaluation management platform runs on a plurality of terminal devices and is in communication interaction with the cloud database. Any terminal device is bound with a user account, and the user account can be directed to an enterprise or a staff. In the present invention, a block chain may be configured for each user/terminal device based on the user attributes contained in each user account. The blockchain is used for recording the evaluation data of the user in the whole network. In this context, terminal devices may be considered as nodes, each of which initiates or receives the performance evaluation data by operating a performance management platform. In this embodiment, for example, the performance management platform will configure a chain of assessed blocks for user a. After the performance assessment aiming at the user A (assessment object) is broadcasted to the whole network, the related nodes/terminal equipment in the whole network receive the performance assessment notice and evaluate the user A according to the specified rule. And the evaluation data of the node for the user A is received and sorted by the evaluation management platform and written into the block chain. Therefore, the appraisal of the performance of the user A in the whole network is collected into the appraised block chain of the user A. Based on the non-tamper-proof property of the block chain, the invention can ensure that the evaluation data of the appraisal performance truly comes from each node.
More specifically, as shown in fig. 2, an embodiment of the present invention provides a method for storing an assessment, where the method specifically includes:
s100, receiving evaluation data of the assessment object; wherein the assessment data is sent out by nodes in the block chain network.
In this step, it is understood that the performance evaluation data is generated based on the attributes of each node, and includes at least the subject of the performance evaluation, the object (assessment target), and the content of the performance evaluation. More often times, the time of performance assessment generation, the relationship between the subject and the object, and the like are included. In an actual application scenario, it can be known that the assessment data may include assessment results in the form of scores for assessment objects and the like. In this embodiment, the assessment and evaluation data are sent by all nodes participating in assessment of the assessment and evaluation network, and are collected by the assessment and evaluation management platform. It can be understood that the terminal device pointed by the node may be logged in by an individual user or an enterprise user. The invention is not limited thereto. For this reason, the assessment objects may be individual users, such as employees of a certain enterprise; or may be an enterprise. When the assessment request aiming at the assessment object is issued to the whole network, the nodes related to the assessment object in the whole network receive the assessment request. It should be understood that the examination request issued by the enterprise may be an examination request issued by a certain employee or an examination request initiated by a certain employee and directed to a certain enterprise. Or, in some cases, it may be a job seeker who wants to know about a given business and issue assessment requests for that business.
It should be understood that when a qualifying request is issued into the entire network, not all nodes in the entire network will respond to the qualifying request. Or, not all nodes can receive the assessment request. In the present invention, there is also a screening filtering method for qualification for performance evaluation. Generally, only the nodes which pass the performance qualification screening can receive the assessment request, and the assessment objects can be evaluated necessarily according to the assessment request. In the invention, the associated object directly related to the assessment object is set as the node which accords with the evaluation qualification aiming at the assessment object. Generally speaking, the associated object may be the assessment object itself, a friend, a company at which it is located, a company colleague at which it is located, a former company colleague, a client enterprise with business to and from, a supplier enterprise, a partner enterprise, a colleague, and the like. These direct correlations may be determined from the registration information of the node user. For example, node a's graduation school is XX university, and node B's graduation school is also XX university, then there is alumni relationship between the two. Further, node A read at XX university in 2008 + 2014 and node B read at XX university in 2008 + 2014, the two become strong association. In this case, when the assessment object is node a, node B may receive an assessment request regarding assessment object a. Moreover, since a and B are contemporaneous in-life, there is a strong correlation between the two. Finally, the assessment data about the assessment object A uploaded by the node B can obtain larger credible weight. Generally speaking, the filtering method for screening qualification of appraisal of achievement, as shown in fig. 3, may include the following steps:
a10, listening the broadcast request related to the appraisal performance information in the block chain network;
a20, responding to the broadcast request, acquiring an associated object directly related to the assessment object;
a30, determining a target node corresponding to the user attribute of the associated object in the block chain network according to the user attribute of the associated object;
a40, issuing the achievement information to the target node.
In the steps A10-A40, the target node is the node passing the screening. Meanwhile, it can be understood that the user attribute of the associated object in the blockchain network may be a relationship between the verification node and the assessment object through the registration information. In some embodiments, the time limit of the examination can be determined according to the timeliness of the examination. For example, employees who are out of position from a company for more than a year cannot qualify the company; or the node B and the assessment object A are alumni, but the on-school time of the node B and the assessment object A is completely inconsistent, and the time interval is longer. These can be used as the screening principle of the performance nodes. Further, in order to improve the association between the nodes, the method of the present invention may further obtain registration information of all objects in the blockchain network, and define an object in the obtained registration information that is the same as or partially the same as the registration information of the assessment object as having a direct correlation with the assessment object to serve as the association object. Therefore, a corresponding database can be formed for the relationship between the assessment objects and the nodes. In this context, it is also to be understood that the broadcast request relating to performance information may be referred to as a "assessment request". Although the terms are different, they are substantially the same. And will not be described in detail herein.
S200, determining an evaluated block chain related to the user attribute from the plurality of block chains according to the user attribute of the evaluation object; the evaluated block chain is used for recording evaluation data of the nodes in the block chain network aiming at the appraisal objects.
Generally speaking, the assessment objects are nodes existing in the assessment management platform. And as mentioned above, each node is established with a corresponding evaluated block chain for recording the evaluation data of the overall network for the node. It can be understood that the terminal device can enter the performance management platform through the corresponding account login to become a node in the blockchain network. Based on the registration information on the performance management platform, corresponding user attributes may be formed. Because the user attribute corresponds to the node, the corresponding node can be determined according to the user attribute, and then the evaluated block chain associated with the node is determined. And the evaluated blockchain is used for recording evaluation data of the nodes in the blockchain network aiming at the evaluation objects. Based on the evaluated block chain, the evaluation of the assessment objects in the whole network can be completely recorded.
Further, when determining the evaluated block chain, a preset map corresponding to the user attribute may need to be queried, where the preset map is used to indicate a corresponding relationship between the user attribute and the evaluated block chain. The preset mapping is a mapping preset in an appraisal performance management platform or a cloud database, and mainly reflects the corresponding relation between the user attribute and the evaluated block chain corresponding to the user attribute. Based on the mapping, the evaluated block chain corresponding to the user attribute can be found in a mode of inquiring the user attribute. Therefore, in the present embodiment, if there is a preset mapping associated with the user attribute, the blockchain corresponding to the user attribute in the preset mapping is determined as the evaluated blockchain. However, in some cases, the performance management platform does not establish a corresponding evaluated block chain for the evaluation object, and at this time, there is no preset mapping related to the user attribute. Then, in response to such a non-existent signal, the performance management platform directly creates a blockchain associated with the user attribute and determines the created blockchain as an evaluated blockchain corresponding to the user attribute of the assessment object.
Meanwhile, when the nodes send out the evaluation data of the appraisal results, the evaluation data can be distributed to the whole network through hash operation, digital signature and asymmetric encryption and then collected and sorted by the appraisal results management platform. Therefore, it can be considered that the evaluation content of the assessment target according to the specified regulation and the signature of the assessment target issuing the evaluation content are included in the assessment data. Since the digital signature exists in the performance evaluation data, the performance management platform needs to properly verify the collected performance evaluation data. By respectively verifying the hash operation value and the digital signature of the evaluation content corresponding to the public key and the private key in the asymmetric encryption, whether the evaluation data of the achievement evaluation is tampered after the node is issued and before the evaluation data is collected by the achievement management platform can be understood. And verifying the passed evaluation data of the achievement, showing that the evaluation data of the achievement is not tampered and is really sent out by the node.
S300, generating a second evaluated block on the evaluated block chain based on the evaluation data of the evaluation results and the block head characteristic value of the first evaluated block in the evaluated block chain; the first evaluated block is a previous block of a second evaluated block on the evaluated block chain, and the second evaluated block is used for recording evaluation data of the evaluation results.
In this step, as shown in fig. 7 and 8, the performance management platform may obtain all information in the block header of the first block from the chain of evaluated blocks, and obtain the block header feature value of the first block based on all information in the block header of the first block. Meanwhile, the characteristic value of the evaluation data of the achievement to be stored in the block body of the second block is calculated to obtain the characteristic value of the block body of the second block. And further storing the block head characteristic value of the first block and the block main body characteristic value of the second block to the block head of the second block. And after the evaluation data of the appraisal results are stored in the block main body of the second block, the second block is generated, so that the second block is related to the first block through the block head characteristic value of the first block, and the purpose of connecting the blocks in the block chain in series is realized. On the basis, any modification of the information in the block can be detected by tracing the block head characteristic value of the last block stored in the block head of the block, so that the safety of the evaluation data of the achievement is ensured.
More specifically, for example, an employee or a business logs in the performance management platform through a terminal device to become a node in the blockchain network. Assume employee/Enterprise A is the assessment object. And establishing a block chain L-A corresponding to the employee/enterprise for the employee/enterprise A. The assessment platform issues assessment requests for employees/enterprises A in the blockchain network. Nodes associated with employee/Enterprise A may each receive the assessment request. And the node receiving the assessment request responds to the assessment request and evaluates the assessment results of the employee/enterprise A. Taking employee A as an example herein, the assessment of performance may include two broad categories of work capacity and work attitude. As shown in tables 1 and 2 below:
TABLE 1
TABLE 2
The working capacity can be further subdivided into professional skills, control capacity, analysis and judgment, plan organization and communication coordination; the working attitude may be further subdivided into accountability, cost concept, loyalty, compliance, level of care, and the like. Each classification is endowed with different weight and score, the score is used for the node to judge the score of the assessment object on the classification item, and the weight is the proportion of the score in the overall score. Through the giving of the scores and the weights, all the classifications can be reflected to a certain degree in the assessment, so that the staff can be evaluated more effectively from multiple angles.
While in evaluating a business, the dimensions of the evaluation may vary. For example, the evaluation of the enterprise may include: 1. evaluating the management layer; 2. evaluation of the whole enterprise; 3. evaluation of company culture construction, and the like. Of course, this is merely an example, and the present invention is not limited to the evaluation method.
In the above description, the evaluation data of the node on the assessment object is mainly obtained. Here, the assessment object may be an enterprise or an employee. When the node (enterprise or individual with qualification for A) in the whole network evaluates the employee/enterprise A for the appraisal performance, the appraisal performance is used as appraisal performance information, and the appraisal performance evaluation data is formed after hash operation, digital signature and asymmetric confidentiality. The performance assessment data is subsequently distributed throughout the network. And the appraisal performance management platform collects appraisal performance data aiming at the appraisal object and sent by all relevant nodes and verifies the appraisal performance data. The verified achievement evaluation data will form a new block to be incorporated into employee blockchain L-a for employee a.
In order to better record the activity of the nodes in the blockchain network, the invention can also store the evaluation records of the nodes in the blockchain network. Performance assessment data issued for each node is stored to record node activity in the blockchain network. More specifically, as shown in fig. 4, the recording method includes:
and B10, monitoring the performance evaluation data sent by the node.
In this step, each node in the blockchain network is in a listened state. In this state, any activity sent by the node can be well fed back and monitored. In this embodiment, the assessment data sent by the node is mainly monitored, so that the corresponding operation is performed in time and subsequently according to the assessment data sent by the node.
And B20, when monitoring that the node sends out the appraisal data of the appraisal of the performance, determining a record block chain related to the user attribute of the node from the plurality of block chains according to the user attribute of the node.
It should be understood that in the present invention, there are a plurality of block chains, and each block chain coexists. What is referred to and determined herein is a recording block chain. The record blockchain is used to record the activity of nodes in the blockchain network. In this step, the record blockchain is used to record the behavior of the creditability assessment data sent by the node, so that the exact relationship between the node and the creditability assessment data sent by the node can be determined during tracing. The same way as when the evaluated block chain is determined, when the recording block chain is determined, the preset mapping corresponding to the user attribute of the user is also inquired, and the preset mapping is used for indicating the corresponding relation between the user attribute and the recording block chain; if a preset mapping related to the user attribute of the user exists, determining a block chain corresponding to the user attribute in the preset mapping as the recording block chain; and if the preset mapping related to the user attribute does not exist, creating a blockchain associated with the user attribute of the user, and determining the created blockchain as the record blockchain related to the user attribute of the user. The preset mapping is a mapping preset in an appraisal performance management platform or a cloud database, and mainly reflects the corresponding relation between the user attribute and the evaluated block chain corresponding to the user attribute. Based on the mapping, the evaluated block chain corresponding to the user attribute can be found in a mode of inquiring the user attribute. Therefore, in the present embodiment, if there is a preset mapping associated with the user attribute, the blockchain corresponding to the user attribute in the preset mapping is determined as the evaluated blockchain. However, in some cases, the performance management platform does not establish a corresponding evaluated block chain for the evaluation object, and at this time, there is no preset mapping related to the user attribute. Then, in response to such a non-existent signal, the performance management platform directly creates a blockchain associated with the user attribute and determines the created blockchain as an evaluated blockchain corresponding to the user attribute of the assessment object.
Meanwhile, when the nodes send out the evaluation data of the appraisal results, the evaluation data can be distributed to the whole network through hash operation, digital signature and asymmetric encryption and then collected and sorted by the appraisal results management platform. Therefore, it can be considered that the evaluation content of the assessment target according to the specified regulation and the signature of the assessment target issuing the evaluation content are included in the assessment data. Since the digital signature exists in the performance evaluation data, the performance management platform needs to properly verify the collected performance evaluation data. By respectively verifying the hash operation value and the digital signature of the evaluation content corresponding to the public key and the private key in the asymmetric encryption, whether the evaluation data of the achievement evaluation is tampered after the node is issued and before the evaluation data is collected by the achievement management platform can be understood. And verifying the passed evaluation data of the achievement, showing that the evaluation data of the achievement is not tampered and is really sent out by the node.
B30, generating a second recording block on the recording block chain based on the appraisal data of the record data of the appraisal data of the record blocks; wherein the first recording block is a block before the second recording block on the recording block chain, and the second recording block is used for recording the evaluation data of the achievement.
In this step, as shown in fig. 9 and 10, the achievement management platform may obtain all information in the block header of the first block from the recording block chain, and obtain the block header characteristic value of the first block based on all information in the block header of the first block. Meanwhile, the characteristic value of the evaluation data of the achievement to be stored in the block body of the second block is calculated to obtain the characteristic value of the block body of the second block. And further storing the block head characteristic value of the first block and the block main body characteristic value of the second block to the block head of the second block. And after the evaluation data of the appraisal results are stored in the block main body of the second block, the second block is generated, so that the second block is related to the first block through the block head characteristic value of the first block, and the purpose of connecting the blocks in the block chain in series is realized. On the basis, any modification of the information in the block can be detected by tracing the block head characteristic value of the last block stored in the block head of the block, so that the safety of the evaluation data of the achievement is ensured.
In a further embodiment, the present invention may also construct an overall chain, as shown in fig. 5 and 6, for storing the performance evaluation data stored in the above-described review blockchain and record blockchain. Or, it is equivalent to recording all activities in the whole assessment system. In the above, both the assessed blockchain and the record blockchain are used to store only performance evaluation data associated with a single node. The evaluation blockchain stores the evaluation data of the performance aiming at the single node, and the recording blockchain stores all the evaluation data of the performance issued by the single node. The two blockchains can also authenticate each other. For example, if the record "node B evaluates node a" is found in the evaluated block chain associated with node a, and the record "node B evaluates node a" is also found in the record block chain of node B, the two records are mutually verified, and it can be determined that the content stored in the evaluated block chain associated with node a is authentic. Similarly, it is also possible to verify that the contents stored in the record block chain of the node B are authentic. In a further embodiment, the constructed overall chain may store the performance assessment data stored in the above-described assessed blockchain and record blockchain, i.e., all activities in the blockchain network.
In the embodiment, the performance evaluation actions of each node in the blockchain network for sending the performance evaluation data are monitored; the assessment data at least comprises a subject node, an object node and assessment content information of the subject node to the object node according to specified regulations in the block chain network. The subject node can evaluate the object node according to the assessment request. For example, the subject node a evaluates the object node B (assessment object). The content information of the evaluation can be as described above, and the evaluation of the performance evaluation can comprise two broad categories of working capacity and working attitude, and the like. And will not be described in detail herein.
After the performance evaluation action of the nodes in the block chain network is monitored, responding to the performance evaluation action, and writing the performance evaluation data into a first block chain for storing the performance evaluation data sent by the main body node according to the user attribute corresponding to the main body node. It should be understood that the first blockchain described herein, i.e., the aforementioned record blockchain, is used to store the record of the performance activity of the subject node.
And meanwhile, when responding to the appraisal performance action, writing the appraisal performance data into a second block chain for storing the appraisal performance data aiming at the object node according to the user attribute corresponding to the object node. The second blockchain described herein, namely the aforementioned assessed blockchain, is used for storing records of the performance activities received by the object node (assessment object) from other nodes.
Thereafter, a third blockchain for recording all performance actions is determined. The third blockchain, i.e. the aforementioned global chain, is used to record all activities in the blockchain network, including, for example, the evaluation of node a on node B, the evaluation of node B on node C, and the evaluation of node C on node D. In general, the performance activities belonging to the blockchain will be stored without restriction on the user attributes of the nodes. In a more specific step of writing a third block chain, generating a second block on the third block chain based on the performance evaluation data stored in the first and second block chains and the block head feature value of the first block of the third block chain; and the first block is a block which is previous to the second block on the third block chain, and the second block is used for recording the appraisal data of the achievement stored in the first block chain and the second block chain.
Similarly, in the writing process of the third block chain (general chain), the verification steps for the first block chain (recording block chain) and the second block chain (evaluated block chain) are also required as described above. And will not be described in detail herein.
After the above description, it can be understood that in the method of the present invention, three parallel block chains can be constructed, but can influence and verify each other: the system comprises a general chain, an evaluated block chain and a recording block chain. Wherein, there may be more than one evaluated blockchain and recording blockchain at the same time, because both are generated based on nodes. Generally speaking, there are as many links of the block to be evaluated and as many links of the block to be recorded as there are nodes. And the general chain is only one and is used for recording all activity conditions in the whole block chain network.
Generally, when a business or an employee initiates a qualification request for a certain assessment object, the employee or the business will need to determine the assessment information, which includes the assessment object and the qualification content. The assessment content may include various aspects of work capacity, work attitude, and the like. Then, an assessment form is designed according to the assessment content and the assessment objects. The form may be as shown in tables 1 and 2, or may be other similar forms. The form at least comprises assessment objects and specific assessment contents. When the examination request is sent out, the examination object and the examination form are included in the examination and request. The assessment contents are displayed in the assessment form in the form of characters or images and the like. The originator of the assessment request (the originating node) can also determine the assessment period when the assessment request is issued. That is, the assessment is completed within a specified period. Performance assessment data submitted beyond this period will not be accepted. The assessment period is limited in the assessment request in a program mode, so that the nodes receiving the assessment request can know the specific period of the assessment at the same time. Of course, as described above, only the related object directly related to the assessment object can receive the assessment request, or only the related object directly related to the assessment object can respond to the assessment request, so as to filter the influence of other unrelated persons on the assessment object. In addition, the assessment contents presented in the assessment form can be weighted according to the classification and specific indexes. The weight is determined based on a more reasonable score of the assessment object. In the process, after receiving the assessment request, the nodes in the block chain network evaluate the assessment objects according to the assessment request on the assessment form contained in the assessment request. And after the evaluation is finished, the node uploads the evaluation result.

In this way, all the appraisal results can be positioned according to time, appraisers and appraised persons. In some embodiments, it may even include the total time taken for performance assessment, the location of performance assessment, the relationship between the rater and the ratee being, and the like. The distance is used herein only and is not particularly limited. The appraisal data of the appraisal results uploaded by the nodes can be distributed to the whole network through hash operation, digital signature and asymmetric encryption and then collected and sorted by the appraisal results management platform. Therefore, it can be considered that the evaluation content of the assessment target according to the specified regulation and the signature of the assessment target issuing the evaluation content are included in the assessment data. Since the digital signature exists in the performance evaluation data, the performance management platform needs to properly verify the collected performance evaluation data. By respectively verifying the hash operation value and the digital signature of the evaluation content corresponding to the public key and the private key in the asymmetric encryption, whether the evaluation data of the achievement evaluation is tampered after the node is issued and before the evaluation data is collected by the achievement management platform can be understood. And verifying the passed evaluation data of the achievement, showing that the evaluation data of the achievement is not tampered and is really sent out by the node. After the assessment data is collected by the assessment performance management platform, the assessed block chain, the recording block chain and the general chain can be determined, and the assessment data is written into the corresponding assessed block chain, the recording block chain and the general chain. The corresponding performance assessment data is time stamped when written into the blockchain for subsequent tracking. Based on the above, it can be known that the total network of the activities of the performance evaluation can be stored by at least three block chains at the same time.
