Abstract
The invention provides a method for inputting graph keys through a mouse touchpad. According to the technical scheme, the problem that when fingerprint identification is carried out, use of a user is influenced due to the fact that a finger is injured is solved, only when the user inputs correct graph keys on a mouse, the mouse can normally start a computer, and otherwise, the computer cannot be started. Due to the fact that difficulty of cracking of graphical key information is much higher than that of the form of a power-on password, safety of the notebook computer is improved.
Description
Technical field
What the present invention relates to is the use security fields of computing machine, the especially method of utilizing mouse touch pad tablet pattern key to mobile devices such as notebook computers.
Background technology
In the prior art, known technology is that notebook computer is because volume is small and exquisite, portable performance, obtain liking of increasing user, but also just because of its portable performance, make user have too much worry to the security of information in notebook computer, people start its notebook computer to adopt various cipher modes, as adopt startup password or adopt the mode etc. of fingerprint recognition, but also there is the disadvantageous aspect to user in these modes, as common startup password is easily cracked, can directly affect when finger injuries fingerprint recognition user to the use of machine etc., this is the existing weak point of prior art.
Summary of the invention
Object of the present invention is exactly for the existing deficiency of prior art, and provide a kind of technical scheme of utilizing mouse touch pad tablet pattern encryption key method, finger injuries when this scheme has solved fingerprint recognition and produce affect the problem that user uses, only have user on mouse, to input after correct figure key, mouse could be by computer normal boot-strap, otherwise machine will can not start, and patterned key information cracks difficulty far above the body of startup password, improved security.
This programme is achieved by the following technical measures: a kind of method of utilizing mouse touch pad tablet pattern key, is characterized in that comprising the steps:
1) touch pad is carried out to subregion, form a plurality of positions subregion;
2) user inputs key figure, the some position subregion identification figure on touch pad, and graphical information is converted to character string sequence stores;
3) judgement touch pad has or not figure input, if had, enters step 4, otherwise does not move;
4) when touch pad has figure input, the figure of the some position subregion identification input on touch pad, and corresponding graphical information is converted to character string sequence, the character string sequence of the character string sequence of conversion and storage is compared, if the figure of input is identical with key figure, computer booting, if the figure of input is not identical with key figure, repeating step 3).
In described step 2) in, it is twice that user inputs key figure, comprise the steps: that a, user input after key figure first, point position subregion identification figure on touch pad, and graphical information is converted to character string sequence interim storage, b, user be tablet pattern key again, point position subregion identification figure on touch pad, and the graphical information of input is again converted to character string sequence, c, the character string sequence of twice is compared, if identical, character string sequence is carried out to permanent storage, if not identical, repeating step a.
In described step 1), touch-screen is divided into respectively to 255 subregions along x axle and y axle both direction.
Point position subregion described in above-mentioned each step is when identification figure, if figure is through a some position subregion, the character of this some position subregion is 1, and figure does not have certain any subregion of process, the character of this some position subregion is 0, and the institute a little character of a subregion has formed character string sequence.
The beneficial effect of this programme can be learnt according to the narration to such scheme, due in this scheme a little position subregion, be convenient to program to the extraction of a position and the comparison to figure, the accuracy rate of raising to the extraction rate of graphical user key and identification, simultaneously, such design has also improved the some position recognition accuracy that touches mouse, and the input precision that makes to touch mouse is higher, more accurate;
As can be seen here, the present invention compared with prior art, has outstanding substantive distinguishing features and significant progressive, and the beneficial effect of its enforcement is also apparent.

Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
The method of utilizing mouse touch pad tablet pattern key of this programme, is characterized in that comprising the steps:
1) touch pad touch-screen is divided into respectively to 255 subregions along x axle and y axle both direction;
2) user to input key figure be twice, comprise the steps: that a, user input after key figure first, point position subregion identification figure on touch pad, and graphical information is converted to character string sequence interim storage, b, user be tablet pattern key again, point position subregion identification figure on touch pad, and the graphical information of input is again converted to character string sequence, c, the character string sequence of twice is compared, if identical, character string sequence is carried out to permanent storage, if not identical, repeating step a., the some position subregion identification figure on touch pad, and graphical information is converted to character string sequence stores;
3) judgement touch pad has or not figure input, if had, enters step 4, otherwise does not move;
4) when touch pad has figure input, the figure of the some position subregion identification input on touch pad, and corresponding graphical information is converted to character string sequence, the character string sequence of the character string sequence of conversion and storage is compared, if the figure of input is identical with key figure, computer booting, if the figure of input is not identical with key figure, repeating step 3).
Point position subregion described in above-mentioned each step is when identification figure, if figure is through a some position subregion, the character of this some position subregion is 1, and figure does not have certain any subregion of process, the character of this some position subregion is 0, and the institute a little character of a subregion has formed character string sequence.
The present invention is not limited in above-mentioned embodiment, and the variation that those of ordinary skills make in essential scope of the present invention, remodeling, interpolation or replacement also should belong to protection scope of the present invention.
