The invention discloses a digital forensics method based on blockchain privacy protection and fine-grained access control. The first supervisor creates a digital forensics transaction, initiates a digital forensics transaction request to the second supervisor, and transmits important information of the digital forensics transaction to the second supervisor. Two regulators; the second regulator generates attribute encryption intermediate parameters through the encryption module, and authorizes and publishes them in the blockchain; after the first regulator is authorized, it obtains the shard key from the key management institution module through the authorization information, and Combine the fragmentation keys to generate a decryption key, and the data acquisition module collects data in the storage system through the decryption key; the first supervisor analyzes the data after collecting the data, and obtains the data analysis results; then generates a digital report for forensics, and the forensics is completed ; The present invention utilizes the potential of blockchain and smart contracts, and designs encryption primitives to build a blockchain-based Internet of Vehicles digital forensics solution, which has auditability, privacy protection and fine-grained data access control.

The embodiment of the invention provides a voice recognizing method and a voice recognizing device based on a block chain, a medium and an electronic device. The voice recognizing method based on theblock chain comprises the following steps: storing labelled historical voice data in the block chain; and if a new block of the current voice information is generated in the block chain, triggering anacoustic model and a linguistic model finishing through training to recognize the current voice information, and outputting the current text information corresponding to the current voice information, wherein the acoustic model and the linguistic model are obtained through training by adopting the historical voice data labelled in the block chain. According to the technical scheme of the embodiment of the invention, the voice data of the user is stored by adopting the block chain technology, and the recognition for the current novice is carried out based on the stored historical voice data.

The invention discloses a method for controlling the access to a shared component of a leveled partition, wherein, the method does not allow the upper / lower level relations between any two shared components in a network to be circulated; each shared component comprises one or more than one users and one or more than one partitions, the users and the partitions are assigned an integrity level, andthe documents are stored in the partitions; particularly, the integrity level is comparable numerals in sequence; and the integrity level of a document can be determined by the partition of the document, and the confidentiality level thereof can be determined by the level of the shared component in the network. The invention provides the shared component of a leveled partition for the constructionof a security model, a complex problem can be divided into a few minor problems, therefore, the problems can be solved locally, and the invention has the advantages of decentralized rights and uniform availability, confidentiality and integrity.
