Various embodiments of the method of the present invention are presented in terms of the above-described hardware architecture.
Referring to fig. 2, in a first embodiment of the vehicle data processing method of the present invention, the vehicle data processing method includes:
step S100, receiving a vehicle data message, and screening out vehicle data without desensitization of sensitive information from the vehicle data message;
in order to obtain the technical condition of the vehicle in actual use, the performance change condition of each component of the vehicle is monitored, the vehicle manufacturer collects vehicle data messages related to the vehicles sold by the manufacturer at intervals, and the vehicle data messages are collected through a CAN bus and collected. The vehicle data message typically includes vehicle dynamics status, operability status, safety status, exhaust emissions status, vehicle appearance, and the like. In this embodiment, the vehicle dynamic performance conditions include vehicle battery conditions, vehicle motor conditions, and the like, the safety performance conditions include whether a vehicle body frame is deformed or bent, safety belt conditions, and/or airbag conditions, and the like, and the sensitive information includes driver information, license plate numbers, vehicle identification codes, and other identification information having an identification function, and may also be performance information that is inconvenient to be leaked to a third party manufacturer, such as use state information of a new technology; specific information such as navigation information, positioning information, voice information and the like in the using process of the vehicle is sensitive information and is set by a person in the field.
After the vehicle data message is received, the vehicle message data can be divided into two types according to the ways of keyword query, desensitization identification information reading and the like and according to whether the sensitive information is desensitized, and the vehicle data which is not desensitized and the vehicle data which is desensitized are not desensitized. For example: after desensitization processing is carried out, desensitization identification information can be added into vehicle message data, and then whether desensitization processing is finished or not can be determined by inquiring whether desensitization identification information exists or not.
S200, encrypting the non-desensitized sensitive information;
sensitive information in the vehicle data message often includes owner privacy, so that the sensitive information needs to be encrypted before the vehicle data message is further processed or forwarded to protect the owner privacy. The sensitive information can be encrypted by using a certain encryption method alone or by using a combination of multiple encryption algorithms. For example, the vehicle identification code can be encrypted by using a message digest encryption algorithm, an advanced encryption standard algorithm, or a combination of the two encryption algorithms.
Step S300, updating the non-desensitized sensitive information in the vehicle data message into correspondingly encrypted sensitive information to generate a new vehicle data message;
and encrypting the non-desensitized sensitive information into a new character string, and replacing the non-desensitized sensitive information in the vehicle data message by using the new character string so as to convert the vehicle data message into a new vehicle data message. In the embodiment, if the new character string is the same as the original sensitive information in length, the new character string is directly used for filling in the position of the original sensitive information; if the length of the new character string is different from that of the original sensitive information, the new character string needs to be correspondingly processed, so that the length of the processed character string is the same as that of the original sensitive information, and then the processed character string is used for filling in the position of the original sensitive information.
The new vehicle data message can be stored in a processing platform of a vehicle factory for forwarding the message or performing the next processing. In this embodiment, the sensitive information before encryption and the sensitive information after encryption need to be stored in the redis cluster in a one-to-one manner for subsequent query.
Referring to fig. 3, in an embodiment, the step S200 includes:
step S210, encrypting the non-desensitized sensitive information according to an MD5 algorithm to generate a character string corresponding to the sensitive information;
the MD5 algorithm is a widely used cryptographic hash function in the field of computer security to provide integrity protection for messages. According to this algorithm, there is one and only one unique MD5 information value, whether a video file, an audio file, or any other type of file. According to the MD5 algorithm, after an MD5 information value of an arbitrary length is input, four 32-bit data are generated through a program flow, and then the four 32-bit data are combined to output a hash value of a fixed length of 128 bits.
Step S220, extracting characters with a preset number from a preset number of digits in the character string, and performing one-to-one conversion on the characters with the preset number according to a preset mapping relation to generate encrypted sensitive information.
After the MD5 algorithm, information of any length is converted into a 128-bit hash value, and the length of the encrypted character string is inconsistent with the length of the original sensitive information, so that before the original sensitive information is replaced by the encrypted character string, the encrypted character string needs to be processed first, so that the length of the encrypted character string is equal to the length of the original sensitive information, and the generated new vehicle datagram is the same as the original vehicle datagram in word number. In this embodiment, a preset number of characters are extracted from a preset number of bits of a character string, and then the preset number of characters are converted one by one according to a preset mapping relationship. The extraction method of the character string is preset according to a certain rule by the person skilled in the art. For example, when the sensitive information encrypted by MD5 is a vehicle identification code, the original vehicle identification code is composed of seventeen letters or numbers, so seventeen letters or numbers also need to be extracted from the 128-bit hash value after encryption, and seventeen bits may be taken from the 1 st bit of the character string or seventeen bits may be taken from the tenth bit of the character string.
In this embodiment, the one-to-one conversion of the preset number of characters according to the preset mapping relationship may be to add one to all numbers in the characters, or to convert upper-case letters in the characters into corresponding lower-case letters, or to convert lower-case letters in the characters into upper-case letters.
In one embodiment, step S100 includes:
receiving a vehicle data message, and extracting sensitive information from the vehicle data message one by one;
judging whether the sensitive information is encrypted or not;
if not, step S200 is executed.
Receiving a vehicle data message, respectively extracting sensitive information such as driver identity information, license plate numbers, vehicle identification codes and the like from the vehicle data message, sequentially judging whether the sensitive information such as the driver identity information, the license plate numbers, the vehicle identification codes and the like is encrypted, and if the judgment result shows that the sensitive information is not encrypted, encrypting the non-desensitized sensitive information.
Referring to fig. 4, in an embodiment, after the step S400, the method further includes:
step S410, receiving a forwarding request carrying configuration information of a forwarding platform, and screening out vehicle data meeting the requirements of the forwarding platform from the new vehicle data message according to the forwarding request;
step S420, marking the vehicle data meeting the requirement of the forwarding platform as vehicle data to be forwarded;
and step S430, forwarding the vehicle data to be forwarded to a target platform corresponding to the forwarding platform configuration information.
After receiving the vehicle data message, the processing platform of the whole vehicle factory, in addition to performing a sorting analysis on the data, may also forward the vehicle data message to a supplier of vehicle components, such as a vehicle-mounted power battery supplier, a vehicle motor supplier, a vehicle electrical control system supplier, and the like, so as to further evaluate the performance and the life of each component of the vehicle. The data processing platform of the vehicle part supplier is the forwarding platform. The forwarding request sent by the forwarding platform comprises configuration information of the forwarding platform, wherein the configuration information of the forwarding platform comprises the name of the forwarding platform, a port of the forwarding platform, a destination address of the forwarding platform, a vehicle model required by the forwarding platform and the like. The configuration information of the forwarding platform is stored in an interface of the forwarding platform, the front-end processor acquires the required configuration information from the interface, and according to the configuration information of the forwarding platform, vehicle data meeting the requirements of the forwarding platform are screened out from the desensitized new vehicle data message, and the vehicle data are marked as vehicle data to be forwarded. And then according to the configuration information of the forwarding platform, forwarding the vehicle data to be forwarded to the destination address of the forwarding platform by adopting a specified forwarding mode according to a specified communication protocol.
In an embodiment, before step S430, the method further includes:
acquiring configuration information of a forwarding platform, and judging whether the forwarding platform corresponding to the configuration information of the forwarding platform receives message information containing desensitized sensitive information or not according to a preset desensitization processing mapping relation and the configuration information of the forwarding platform;
if so, marking the forwarding platform corresponding to the forwarding platform configuration information as a target platform;
if not, marking the forwarding platform corresponding to the configuration information of the forwarding platform as a non-target platform.
The configuration information of the forwarding platform also includes whether the forwarding platform receives message information containing desensitized sensitive information. The interface of the forwarding platform comprises desensitization information related fields, the front-end processor queries desensitization processing mapping relations corresponding to the desensitization information related fields after reading the desensitization information related fields, and then judges whether the forwarding platform receives message information containing desensitization sensitive information or not according to the desensitization processing mapping relations. And if the query result is that the forwarding platform receives the message information containing the desensitized sensitive information, marking the forwarding platform as a target platform capable of forwarding the message information, and caching the configuration information of the forwarding platform.
In one embodiment, step S410 includes:
acquiring configuration information of a forwarding platform, and acquiring a vehicle identifier meeting the requirements of the forwarding platform according to the configuration information of the forwarding platform;
and extracting the corresponding vehicle data from the new vehicle data message according to the vehicle identification.
The configuration information of the forwarding platform further comprises a vehicle identifier meeting the requirements of the forwarding platform, wherein the vehicle identifier can be the model of the vehicle, the production time of the vehicle, the engine model of the vehicle and the like. For example, the forwarding platform belongs to a certain power battery manufacturer, and the power battery manufacturer only provides a power battery for a vehicle of type a in a whole vehicle manufacturer, so that the forwarding platform only needs vehicle data of the vehicle of type a, and the vehicle identifier at this time is the type a vehicle type.
In an embodiment, the step of acquiring the forwarding platform configuration information, and determining whether the forwarding platform corresponding to the forwarding platform configuration information receives the message information including the desensitized sensitive information according to a preset desensitization processing mapping relationship and the forwarding platform configuration information includes:
acquiring configuration information of a forwarding platform, and reading a desensitization identification field from the configuration information of the forwarding platform; and judging whether the forwarding platform corresponding to the configuration information of the forwarding platform receives the message information containing the desensitized sensitive information or not according to the desensitization identification field.
For example, the desensitization information related field read by the front-end processor from the forwarding platform interface is isVincry, and the desensitization processing mapping relation corresponding to the isVincry obtained by querying is as follows: -1 represents that the forwarding platform receives the message information containing desensitized sensitive information, and 0 represents that the forwarding platform does not receive the message information containing desensitized sensitive information. If the query result is-1, caching the configuration information of the forwarding platform, and marking the forwarding platform as a target platform.
In an embodiment, after step S430, the method further includes:
and recording the vehicle corresponding to the forwarded vehicle data, and recording the non-desensitized sensitive information and the corresponding desensitized sensitive information of the vehicle.
