Abstract

The invention relates to an anti-theft device for electronic devices, especially mobile devices such as a personal computer or PDA's, using a time switching device in connection with a password request.

Description

The theft preventing method of mobile electronic device
Technical field
The present invention relates to combine with timing device at password be used for electronic equipment under the situation about using, particularly as the theft preventing method of the mobile device of mobile personal computer or PDA.
Background technology
The electronic equipment of data processing is temporarily rented the user who holds educational activities in educational institution.Be used as antitheft to this at present simple password protection.If the debit does not deliberately hand to the third party to electronic equipment with password, then this password is known to relative users and this password only is used as antitheft certainly.
Publish document " Method and Apparatus for Conveniently ResettingElectronic Log of Computer System " and disclose a method, interrupt the out of service automatically of computer system in the method thus, promptly the user of computer system carry out an action, such as click the mouse, rolling mouse, sound input or knock keyboard.Along with interruption out of service, in this time interval that resets, after this time interval, begin the next out of service of operating system.
Publish document US 5,699,514 and described an access control system, this system occurs towards the system of two-stage and with former code and one code.If the user wants to visit this system, the user imports its former code, and this former code compares with time code in system then.If two code matches, then the user acquires the access right of system.If the user is the former code of input error repeatedly, then the user only could visit this system behind former code of input and time code once again in system.
Publish document US 6,014,764 and proposed a security system, in this system, prevent the visit of workstation or data medium thus and prevent to steal data or data medium, promptly during unauthorized access, detect safety signal, for example alarm signal, alarm.If input error password very repeatedly, then alarm signal alarm is interrupted the program of security system or is interrupted power supply.
Summary of the invention
The present invention is based on following technical matters, propose one be used for equipment, mainly be to want the electronic equipment hired out or the anti-theft protection of computer equipment, interrupting this equipment through after lending the time for the debit or the third party.
Measure by the following technical programs solves this technical problem.
The theft preventing method that under the situation of using timing device, is used for mobile personal computer or PDA, it is characterized in that, through forbid the operation of equipment after the limiting time by timing device, only by can reset timing device and make equipment rerun the time of pre-qualification of password at the back timing device that resets.
The present invention also comprises the useful expansion based on technique scheme.
By means of the timing device that surmounts simple challenge protection, this equipment is through the operation that is under an embargo after the limiting time, and this equipment of only entering password could normally move once again to this.Wherein only the password by known timing device, personnel could activate forbidden equipment once again.Under normal circumstances these personnel are not debit itself but the representative of educational institution.By the password timing device that in output state, resets once again.
The representative of educational institution configuration timing unit and with password protection.If reach the time of qualification, then owing to forbid making equipment can not operation and user or debit can not re-use this equipment.In order to open the representative that to deliver this equipment educational institution.
Can change use valuably and improve the theft preventing method that is used for mobile electronic device by the zones of different that timing device is integrated in equipment.To this suggestion:
1. timing device is integrated in the BIOS of equipment oneself,
2. timing device is integrated in the power supply of equipment oneself,
3. timing device is integrated in the operating system of equipment.
Description of drawings
According to embodiment illustrated in the accompanying drawings the present invention is described below.Unique accompanying drawing has pointed out to be used for the block scheme of the anti-theft device of mobile electronic device.
Embodiment
This is started the theft preventing method that is used for mobile electronic device at moment T=0, pass through the time T of timing device constantly and forbid this equipment at this.For activate this equipment password again, such as informing that password is essential, equipment keeps forbidding under the situation of using wrong password or unknown password, up to entering password.
If import correct password then releasing arrangement, the timer of timing device is once again by zero setting.
Be indifferent to borrower's crime of illegal selling or presenting cultural relics of private collection or deliberately hand to the third party's situation by this equipment of the method according to this invention.The software and hardware that can when regular presentation apparatus, under the situation that educational institution is authorized, update the equipment in addition.

Claims (10)

1. the theft preventing method that under the situation of using timing device, is used for mobile personal computer, it is characterized in that, through forbid the operation of equipment after the limiting time by timing device, only by can reset timing device and make equipment rerun the time of pre-qualification of password at the back timing device that resets.
2. according to the theft preventing method that is used for mobile personal computer of claim 1, it is characterized in that timing device is integrated in the BIOS of equipment.
