Step 200: and encrypting the payment card number and the collection card number to obtain a first transaction ciphertext.
Specifically, the transaction time is not encrypted during encryption, so that the same key value can be generated when the payment card number transfers to the collection card number for many times, the data conflict can be solved, and whether the first transaction ciphertext exists in a preset data table or not can be judged conveniently. By setting the index value and avoiding encrypting the transaction time, the processing can be completed under the condition that the transaction data is encrypted, and the processing result is obtained.

Specifically, the preset data table may include a plurality of transaction ciphertexts. The first transaction ciphertext may be sent to a data processing device, so that the data processing device determines whether the first transaction ciphertext exists in a preset data table, if yes, and if the transaction time in the transaction data is different from the transaction time in the transaction data, the transaction time corresponding to the first transaction ciphertext in the preset data table is replaced by the transaction time in the transaction data, and an index value corresponding to the first transaction ciphertext is added by 1, so that a processing process of the transaction data is completed; the preset data table may be stored in the data processing device, including but not limited to a server.

Step 302: and storing the corresponding relation among the first transaction ciphertext, the index value thereof and the transaction time in the transaction data into the preset data table.
To increase the reliability of the key stream generation and thus the encryption of the transaction data, as shown in fig. 2, in one embodiment, step 200 includes:
step 201: detecting whether a key stream corresponding to the payment card number and the collection card number exists in a prestored key stream relation table, if not, generating a key stream corresponding to the payment card number and the collection card number by applying an asymmetric encryption algorithm, and storing the corresponding relation among the payment card number, the collection card number and the key stream into the prestored key stream relation table.
In particular, the pre-stored key stream relationship table may be pre-stored in a database in the transaction data processing system.
Step 202: and encrypting the payment card number and the collection card number by using the key stream to obtain a first transaction ciphertext.
For example, assuming the payment card number cardA and the collection card number cardB, the first transaction ciphertext is encry (cardA + cardB).
To increase the efficiency of the application of the keystream and thus the encryption of the transaction data, in one embodiment, step 200 includes:
Step 203: detecting whether a key stream corresponding to the payment card number and the collection card number exists in a prestored key stream relation table, and if so, encrypting the payment card number and the collection card number by using the key stream to obtain a first transaction ciphertext; wherein the pre-stored key stream relation table comprises: and the corresponding relation among the payment card number, the collection card number and the key stream.
To improve the reliability of the encryption of the transaction data, as shown in fig. 3, in one embodiment, the transaction data further includes: a transaction type; correspondingly, the encrypting the payment card number and the collection card number by using the key stream in step 203 to obtain a first transaction ciphertext includes:
Step 2031: and obtaining a key corresponding to the transaction type, and encrypting the payment card number and the collection card number by applying the key corresponding to the transaction type to obtain a second transaction ciphertext.
Specifically, the transaction types may include: consumption, cash withdrawal, transfer, pre-authorization, and installment transaction types, etc. The correspondence between the transaction type and the key may be pre-stored in a database in the transaction data processing system.
Step 2032: and encrypting the second transaction ciphertext by using the key stream to obtain a first transaction ciphertext.
In order to obtain the transfer times by processing the transaction data, and avoid the leakage of the transaction data while ensuring the transfer times, in one embodiment, the adding 1 to the index value corresponding to the first transaction ciphertext in step 300 includes: if the transaction type is the transfer type, determining that the index value is the transfer number, and adding 1 to the transfer number corresponding to the first transaction ciphertext.
Specifically, the transfer number may represent a result of processing the transaction data.
To improve reliability of data storage, in one embodiment, step 300 further comprises:
Step 400: and splicing the first transaction ciphertext and the transaction time in the transaction data into a second transaction ciphertext, and storing the second transaction ciphertext and the index value in the form of key value pairs.
Specifically, the second transaction ciphertext may be used as a key, and the index value may be used as a value corresponding to the key.
In order to further explain the scheme, the application provides an application example of a transaction data processing method, which is specifically described as follows:
step 1: and dynamically encrypting the data based on different user characteristic parameters aiming at a series of data processing performed according to the client information in the banking system. When a user transfers the card number B once by using the card number A at a certain moment, the user, the card number A and the card number B are different indexes, and the corresponding values are detailed data; the number of times the user transferred to card number B has recently been a type of feature. From the perspective of data computation, if information representing the identity of a user, time dimension information, action information, and numerical information are known, a certain type of action of the user can be processed.
Step 2: the obtained data are expanded, and the card number A and the card number B represent indexes to be processed of the data, and are encrypted according to an initial key stream to form a key, and an RSA encryption technology can be adopted for an encryption algorithm.
Step 3: the time dimension information is used as a key index of data calculation and is directly spliced with the generated key value, and the method has the advantages that if the time value is also put into encryption logic, the same key value is inevitably generated, and the data conflict is solved.
Step 4: and processing the similar indexes, after the key encryption processing, acquiring the numerical value corresponding to the original key, and performing data coverage. If at some time timeA user userA uses card number cardA to transfer cardB for the first time and the same operation is performed the next day, processing logic is: the cada and the carbb are processed by a key stream to form a key, the key is in the form of timeA + encry (cardA + cardB) in a storage structure, the corresponding index value is 1, after the second transaction, the value is obtained and covered, namely the key is changed into timeB + encry (cardA + cardB), and the corresponding index value is accumulated to be 2.
Step 5: and storing the processed characteristic values in a structure of (k, v), so that the direct acquisition of data is convenient.
To further illustrate the present solution, the present application further provides an application example of a transaction data processing method, as shown in fig. 4, where the method includes: acquiring various indexes and corresponding values of data to be processed, such as corresponding values of a payment card number and a collection card number; forming an initial key stream according to a specific index; encrypting the numerical value of the index by using a key stream to generate a key; judging whether the same key exists, if so, acquiring a real-time transaction time stamp and a value corresponding to the key; splicing the generated key values to form a new key; covering the original key; if the same key does not exist, acquiring a real-time transaction time stamp; splicing the generated key values to form a new key; resetting the value; after the value resets or overrides the original key, the value accumulates; acquiring a processed characteristic value; data is stored in k, v form.
