As shown in fig. 1, the present embodiment discloses a brain consciousness-based encryption method, and the solution is to use brain consciousness activities as encryption features, because the brain consciousness activities not only satisfy universality, uniqueness, stability, but also satisfy forgery resistance, concealment, and activity detection resistance, and whether to be forced to use passwords to a certain extent can also be distinguished, and the brain activities generate currents and form electromagnetic waves, which can be captured by coils or electrode plates, that is, simultaneously satisfy collectability, so that the brain consciousness activities as encryption features will satisfy all the characteristic requirements in the above problems, and will also become the safest encryption scheme so far.
The consciousness acquiring device in the embodiment is mainly used for acquiring brain activity signals. The consciousness acquirer mainly comprises four core modules, a signal capturing module, a signal amplifying module, a signal collecting module and a signal storing module. In the signal capturing module, the signal capturing module is mainly used for converting brain activity information into current pulsation information, the core principle is that a coil which is wound into a certain number of turns by using a very fine lead is attached to the scalp, and brain electromagnetic waves form current when passing through the coil, so that the effect of converting brain signals into electric signals is achieved; in the signal amplification module, the collected weak current pulse converted from brain signals is mainly enhanced so as to reach the standard of collection and analysis, and the core principle is that a triode or an equivalent amplification device is connected with external current to amplify the current pulse in the same proportion; in the signal collection module, the current pulse after mainly used will be amplified is recorded as the analog signal, and further convert the analog signal into the binary signal, the core principle of the conversion is to define a pulse maximum value according to the pulse intensity, this maximum value covers all pulse current peak values, and wave peak value in the analog signal is converted into the quota figure according to the wave proportion, and convert this figure into the binary to record; the signal storage module is mainly used for storing the pulse information converted into the binary system to equipment such as a buffer area, a flash memory, a magnetic disk and the like so as to prepare for subsequent analysis.
The activity inducer in this embodiment is mainly used to induce the brain to perform a specific activity. When the brain enters a focusing state, a user is required to perform a period of brain interaction according to an application scene, and the interaction may involve brain activity induced by vision, brain activity induced by movement, and brain activity induced by touch or external reflection, so that the activity inducer mainly comprises three core modules, a vision inducing module, a movement inducing module and an event inducing module. In the visual induction module, a specific picture, which may be a photo, a video or a character, is displayed for a user mainly according to the application scene requirement, so that the brain activity of the user is stimulated, and the corresponding brain activity data is recorded; in the motion induction module, the motion induction module is mainly used for brain activities related to motion under a specific scene, such as raising hands, turning left a steering wheel, running and jumping, and the like, the motion induction is not only suitable for normal people with healthy limbs, but also suitable for amputees, such as amputees, who can imagine walking motion, and thus the motion of the brain can be stimulated, and the motion induction module is very practical for an encryption scene that walking is set to be an encryption characteristic after amputees, and can be used as an unlocking password for driving an artificial limb; in the event induction module, the event induction module is mainly used for recording brain activities when a user interacts with a scene, for example, the user enters a warm room, hears a good-hearing song, is stepped on the toes by a person, is injured by the body and the like, and the external events can also excite the brain activities of the user, so that the characteristics of the brain activities are very useful for unlocking the scene or encrypting private information according to the scene in a live-action game or a VR game, and the effect that the user can decrypt the private information only when the user returns to the current scene again can be achieved.
The consciousness key-sealing device in the embodiment is mainly used for extracting the characteristics of brain activity and generating a key. In the awareness key device, the awareness key device is mainly used for extracting the read brain activity features, the process may need to be performed for many times until stable features can be acquired, and because people who do not have special training often have great derivation ideas along with brain activities, the awareness key device comprises three main core modules, a feature extraction module, a feature convention analysis module and a feature key module. The characteristic extraction module is mainly used for carrying out normalization processing after removing noise from the collected fluctuation data; in the characteristic common divisor analysis module, the method is mainly used for extracting common divisors from multiple sections of normalized fluctuation data, extracting a region with the highest overlapping degree in multiple sections of fluctuation, cutting out the maximum complete overlapping region of the region, generating the fluctuation data of the region into a characteristic value by adopting a data summarization algorithm, requiring a user to perform the same brain recognition interaction again, comparing the extraction characteristics of the fluctuation data which are active again, if the extraction characteristics are not consistent, extracting the data acquisition together as the basic data of common divisor extraction until the common divisor which can be matched repeatedly is extracted, and if the common divisor cannot be obtained in the common divisor calculation process due to the continuous acquisition of the data, resetting the data from the beginning and acquiring the data; in the feature key module, the feature key module is mainly used for generating a fixed key pair by taking the extracted features as the seeds of the key pair, reserving a private key and publishing a convention to the outside.
