Abstract

PROBLEM TO BE SOLVED: To satisfy both the reliability and convenience for prohibiting the use by others and for protecting user's ownership. SOLUTION: This intelligent key accepts the input of personal data and release the lock when the input or its processed content coincides with the contents previously registered. Input of personal data for releasing the lock can be a hard-like input or a soft-like input or a combination or them. Hard-like input may be fingerprint, voice, smell or DNA, and soft-like input may be a coded number, birthday, a school from which the user graduated, blood type, keyword or a personal episode. Particularly, the input of soft type item can be accepted by a voice, sound or character display. Question items for data identification may be more than one, and its content may be placed at random. This system comprises at least a display section 1, input section 2, memory 3, and arithmetic section 4. Also, owner's data may be registered in advance.

Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to an intelligent key having a function of recognizing an owner and releasing a lock when the owner is recognized.
In order to determine whether or not the user is the owner, an input of personal data is accepted, and whether or not the input matches the data of the owner is checked. This collation may be hard, soft, or a combination of both. The input of personal data may be input when you want to unlock, or may be an input for a question about the owner's personal data, and it is necessary to check whether the input or its processing content matches the registered content in advance. Confirm and release the lock if it is determined that they match.

[0002] Various keys have been devised to improve security. Most of the conventionally known ones are based on matching of physical characteristics (eg, geometric shape) (hard side) and those based on cryptography (soft side). Not taken into account. In most cases, the hardware aspects and the software aspects are treated independently. Furthermore, the system has not been constructed from a human-friendly viewpoint,
It has the drawback that it is difficult to achieve both reliability and convenience.

[0003] The present invention relates to an intelligent key characterized in that, when personal data is input, the lock is released when it is determined that the input matches the data of the owner. The input of the personal data for releasing the lock may be a hard input, a soft input, or a combination thereof. Hard inputs include, for example, fingerprints, voices, smells, DNA, and the like, and soft inputs include, for example, personal identification numbers, birthdays, home schools, hometowns, blood types, keywords, and personal episodes. In particular, for software input, the input is accepted by voice or character display. There may be a plurality of questions for data collation, and the contents may be random. Reliability is improved by providing an owner identification function. In addition, in the case of soft input, by registering contents that are familiar to the individual and easy to remember, reliability and convenience are improved as compared with the conventional input of only a password. The reliability can be further improved by combining the hardware input and the software input as described above.

BACKGROUND OF THE INVENTION The present invention can be used for protecting the ownership of an owner, making the use of others impossible. There are many types that require personal identification. For example, credit cards, telephone cards, computer terminals, personal computers, electronic organizers, mobile phones, vehicles (cars, motorcycles, etc.), video cameras, electronic cameras,
Safes, warehouses, building doors and doors. If an intelligent key having a personal identification function is incorporated in these, reliability and convenience are greatly improved. Furthermore, if miniaturization is achieved by integration technology and portability is provided, widespread use can be expected.

2. Description of the Related Art There are various means for protecting the security of the ownership of an owner, but conventionally known means are based on matching of physical characteristics (for example, geometric shapes) or encryption technology. In most cases, the identity of the owner is not sufficiently considered. In most cases, the hardware aspects and the software aspects are treated independently. Furthermore, there is a drawback that the system is not constructed from a human-friendly viewpoint, and it is difficult to achieve both reliability and convenience.

In order to make it impossible for others to use and to protect the ownership of the owner, it is necessary to devise new security means that can satisfy both reliability and convenience. The present invention relates to an intelligent key which receives an input of personal data and releases the lock when it is determined that the input or the processing result matches the data of the owner registered in advance.

Means for Solving the Problems The input of personal data for unlocking is input by hardware or software,
Or a composite of them. Examples of hard inputs include fingerprints, voices, smells, and DNA, and examples of soft inputs include passwords, birthdays, schools of origin,
Hometown, blood type, keywords, personal episodes and more. In particular, for software input, the input is accepted by voice or character display. There may be a plurality of questions for data collation, and the contents may be random. When it is determined that the received input or the processing result matches the data of the owner registered in advance, the lock is released. FIG. 1 shows an example (schematic diagram) of a system diagram of the intelligent key. This system has a display unit that prompts for an input to unlock, an input unit that accepts input, a memory that stores the owner's data, and an operation that compares the received input or its processing result with the data of the owner that has been registered in advance. At least. The arithmetic unit outputs a lock release signal for releasing the lock when it is determined that the received input or the processing result matches the data of the owner registered in advance.
The data of the owner can be registered in advance through the input unit. Here, examples of hardware input and software input will be introduced as examples of the input unit. As the hardware input, for example, an input method by imprinting a fingerprint on the tactile pressure sensor unit can be considered. At present, tactile sensors that use changes in electrical resistance and capacitance have been realized.
A device having a spatial resolution of about 0.1 mm has been developed. By detecting the fingerprint pattern of a specific finger (for example, the index finger of the dominant arm) by the tactile pressure sensor,
Input information for owner identification can be obtained. By referring to the registered data stored in the memory in advance and comparing the input data with the registered data in the arithmetic unit,
Determine if you are the owner. FIG. 2 is a conceptual diagram of an intelligent key having a fingerprint identification function. On the other hand, the software input may be, for example, a voice instruction from a display unit or a verbal input to a question. Ask random questions about the owner ’s birthday, school of origin, hometown, blood type, keywords, personal episodes,
A voice that verbally answers this can be obtained as input information. Similarly, referring to the registered data stored in the memory in advance, the arithmetic unit compares the input data with the registered data, thereby determining whether the user is the owner. FIG. 3 shows a conceptual diagram of an intelligent key having a voice interactive function. FIG. 4 shows an example in which an intelligent key is applied to a building door. If it is determined that the intelligent key is the owner, a lock release signal is sent to the key on the door side to release the lock. FIG. 5 shows an example in which an intelligent key is applied to a computer. If it is determined that the intelligent key is the owner, a lock release signal is sent to the computer, and the lock is released. This makes it possible to use a computer or to connect to a network, thereby improving security. In addition, convenience can be improved by improving the human interface.

The reliability is improved by providing the owner identification function. In addition, in the case of soft input, by registering contents that are familiar to the individual and easy to remember, reliability and convenience are improved as compared with the conventional input of only a password. The reliability can be further improved by combining the hardware input and the software input as described above.
