Abstract
The invention discloses a terminal shutdown method and device as well as a terminal. The terminal shutdown method comprises the following steps: when receiving a shutdown instruction, collecting the current authentication information of a user; authenticating the current authentication information in a Bootloader of the terminal so as to judge whether the user is a legal user; and if the user is a legal user, controlling the terminal to be shut down the terminal, and if the user is an illegal user, controlling the terminal to be in a stolen mode. Through the technical scheme, the illegal users are prevented from decoding the authentication scheme when the terminal is shut down, so as to improve the safety of the authentication when the terminal is shut down.
Description
Technical field
The present invention relates to field of terminal technology, in particular to a kind of terminal closedown method, a kind of terminal closedown device and a kind of terminal.
Background technology
In the related, user is when to terminal closedown, it is not necessary to be authenticated directly just can shutting down, or only inputs simple password determine whether to carry out power-off operation when shutdown.But, if user not being authenticated just directly shutdown, also implying that the positioning function closed a terminal, being so difficult to use family when lost terminal and tracking the position of terminal, and disabled user directly shuts down after stealing terminal and carries out again the operation of brush machine；It addition, the mode of subscription authentication is only carried out by password in the application layer of terminal, disabled user is easy to decryption.
Therefore, when how to improve terminal closedown, the safety of authentication becomes technical problem urgently to be resolved hurrily.
Summary of the invention
The present invention is based on the problems referred to above, it is proposed that a kind of new technical scheme, it is to avoid disabled user cracks authentication scheme during terminal closedown, thus the safety of authentication when improving terminal closedown.
In view of this, a first aspect of the present invention proposes a kind of terminal closedown method, including: when receiving shutdown command, gather the current authentication information of user；Described current authentication information is authenticated by the Bootloader of terminal, to judge that whether described user is for validated user；If described user is validated user, then control described terminal closedown, if described user is disabled user, then controls described terminal and be in stolen pattern.
In this technical scheme, by carrying out user authentication in the Bootloader of terminal, it is to avoid correlation technique carries out user authentication in the application layer of terminal, it is possible to be prevented effectively from authentication scheme when disabled user cracks terminal closedown.And when determining that user is disabled user, control terminal and be in stolen pattern, such terminal is constantly in open state, disabled user cannot be shut down, also just make the disabled user cannot to terminal brush machine, and user can remotely control this terminal under stolen pattern, thus improve the probability that terminal is retrieved.Preferably, disabled user can also use the fingerprint stayed during terminal send to the terminal presetting contact person under stolen pattern, to determine the identity of disabled user.
In technique scheme, it is preferable that before the described terminal of described control is in the step of stolen pattern, including: control described terminal and turn back on.
In this technical scheme, before control terminal is in stolen pattern, controlling terminal and turn back on so that switching to stolen pattern when the system of terminal is properly functioning, thus ensureing the system reliability of operation of terminal.
In any of the above-described technical scheme, it is preferable that the described terminal of described control is in the step of stolen pattern, also includes: position the geographical position at described terminal place, and record described geographical position.
In this technical scheme, by positioning the geographical position at terminal place always, and recording geographical position, so that user understands the geographical position of stolen terminal accurately and in time, further increasing the probability that stolen terminal is retrieved.
In any of the above-described technical scheme, it is preferable that described current authentication information includes one below or its combination: finger print information, iris information, facial information, palmprint information, acoustic information；And described in the Bootloader of terminal, described current authentication information is authenticated, to judge that described user is whether for the step of validated user, specifically includes: mated with the authentication information that prestores by described current authentication information in described Bootloader；If the match is successful, then judge that described user is as validated user, if it fails to match, then judge that described user is as disabled user.
In this technical scheme, current authentication information can be bio information, such as: finger print information, iris information, facial information, palmprint information, acoustic information, judge whether user is validated user by carrying out mating with the authentication information that prestores by current authentication information, thus realizing the user to using terminal to carry out certification quickly and accurately.
In any of the above-described technical scheme, it is preferable that described current authentication information includes: described user presses the force value of described terminal screen；And described in the Bootloader of terminal, described current authentication information is authenticated, to judge that described user is whether for the step of validated user, specifically include: in described Bootloader, obtain the pressure rank corresponding with described force value, and described pressure rank and preset pressure rank are compared；If described pressure rank is consistent with described preset pressure rank, then judge that described user is as validated user, if described pressure rank is inconsistent with described preset pressure rank, then judge that described user is as disabled user.
In this technical scheme, current authentication information can be the force value that user presses terminal screen, by being compared to judge whether user is validated user by the pressure rank belonging to this force value and preset pressure rank, thus realizing the user to using terminal to carry out certification quickly and accurately.
A second aspect of the present invention proposes a kind of terminal closedown device, including: collecting unit, for when receiving shutdown command, gathering the current authentication information of user；Judging unit, for being authenticated described current authentication information, to judge that whether described user is for validated user in the Bootloader of terminal；First control unit, for when described user is validated user, controlling described terminal closedown, when described user is disabled user, controls described terminal and be in stolen pattern.
In this technical scheme, by carrying out user authentication in the Bootloader of terminal, it is to avoid correlation technique carries out user authentication in the application layer of terminal, it is possible to be prevented effectively from authentication scheme when disabled user cracks terminal closedown.And when determining that user is disabled user, control terminal and be in stolen pattern, such terminal is constantly in open state, disabled user cannot be shut down, also just make the disabled user cannot to terminal brush machine, and user can remotely control this terminal under stolen pattern, thus improve the probability that terminal is retrieved.Preferably, disabled user can also use the fingerprint stayed during terminal send to the other-end presetting contact person under stolen pattern, to determine the identity of disabled user.
In technique scheme, it is preferable that also include: the second control unit, it is used for controlling described terminal and turns back on.
In this technical scheme, before control terminal is in stolen pattern, controlling terminal and turn back on so that switching to stolen pattern when the system of terminal is properly functioning, thus ensureing the system reliability of operation of terminal.
