Abstract

The present invention is related to a method for verifying authorized access, and is specifically a method for verifying authorized access with an improved means of inputting a password, so as to prevent a spectator observing the inputting process from learning the password, and to facilitate memorizing the password. In said method, a user memorizes as a ‘user-friendly’ password, in relation to a reference background predetermined by the user, at least one locations as assignable districts, their order, and their number, but inputs the password by inputting codes that are shown at locations of the assignable districts consisting the memorized password. These codes are randomly determined and shown to the user, so that the codes as password change each time whenever the user asks to enter the system.

Claims

1. A method for verifying authorized access by creating a password inputting rule for assignable districts of a predetermined reference background, the method comprising the steps of:

1) inputting a user identification by a user;

(2) determining whether the user identification is an authorized user identification, if positive, then proceeding to step (41), if negative, then proceeding to the next step;

(3) displaying an image according to a predetermined reference background to indicate an inputting rule for assignable districts of the reference background, so as to facilitate inputting and setting of a password which consists of one or multiple the assignable districts;

(4) displaying a dynamically constructed image according to a predetermined reference background to indicate an inputting rule that is produced dynamically and corresponds to assignable districts of the reference background, so as to facilitate inputting of a password, and then proceeding to verify validity of the password,

wherein the step (4) further comprises the steps of;

(41) dynamically producing the inputting rule to determine random codes corresponding to assignable districts, these assignable districts including all assignable districts contained in predetermined district sequence as password;

(42) displaying an image containing a predetermined reference background corresponding to the user identification and the random codes determined in step (41), so that individual the random codes are positioned respectively to corresponding assignable districts that are corresponding to the scope of the reference background;

(43) inputting a random code sequence as to be verified, the random code sequence as to be verified including one or multiple the random codes;

(44) producing a random code sequence as password according to predetermined the district sequence as password and the dynamical inputting rule, followed by determining whether the random code sequence as password equals the random code sequence as to be verified, if positive, then proceeding to step (47), if negative, then proceeding to the next step;

(45) determining whether error frequency is greater than a predetermined value, if positive, then proceeding to the next step, if negative, then proceeding to step (41);

(46) setting the user as disqualified for authorized access, proceeding to step (5);

(47) setting the user as qualified for authorized access, proceeding to step (5); and

(5) end of the process.

2. The method for verifying authorized access of claim 1, wherein said step (3) further comprises the steps of:

(31) determining whether to establish a new essential data, if positive, then proceeding to the next step, if negative, then proceeding to step (5);

(32) displaying an image containing a predetermined reference background and district codes, individual said district code respectively corresponding to one assignable district of said reference background and being distinguishable from a district code corresponding to any other assignable districts;

(33) determining whether to reset reference background, if positive, then proceeding to the next step, if negative, then, proceeding to step (35);

(34) setting of reference background, then proceeding to step (32);

(35) inputting a district sequence as password in terms of inputting corresponding district codes;

(36) determining whether an essential data is valid according to predetermined requirements, if positive, then proceeding to the next step, if negative, then proceeding to step (32), said essential data comprising said user identification, said reference background, data related to defining said assignable districts, and said district sequence as password;

(37) storing said essential data, including said user identification, said reference background, data related to defining said assignable districts, and said district sequence as password;

(38) determining whether to proceed further, if positive, then proceeding to step (1), if negative, then proceeding to step (5).

3. The method for verifying authorized access of claim 2, comprising between said step (31) and said step (32) a further step of:

(311) setting said reference background to consist of M×

N assignable districts arranged in M columns and N rows obtained by dividing a picture in length and breadth into rectangular regions of equivalent dimensions, and setting said district code as a binary sequence, n*m, that is formed by a column number, m, and a row number, n, of corresponding said assignable district, wherein M, N, m, and n are natural numbers, and 1 ≦

m≦

M′

1≦

n≦

N.

4. The method for verifying authorized access of claim 2, comprising between said step (31) and said step (32) a further step of:

(312) setting said reference background to consist of M×

N assignable districts arranged in M columns and N rows that are rectangular regions of equivalent dimensions, individual said rectangular region exhibiting a color which is randomly determined, and said district code being set as a binary sequence, n *m, that is formed by a column number, m, and a row number, n, of corresponding said assignable district, wherein) M, N, m, and n are natural numbers, and 1≦

m≦

M′

1≦

n≦

N.

5. The method for verifying authorized access of claim 1, said step (41) comprising a further step of:

(411)setting said reference background, according to a predetermined essential data, to consist of M×

N assignable districts arranged in M columns and N rows that are rectangular regions of equivalent dimensions, and setting said district code as a binary sequence, n*m, that is formed by a column number, m, and a row number, n, of corresponding said assignable district, wherein M, N, m, and n are natural numbers, and 1≦

m≦

M′

1≦

n≦

N, and said random code being an alpha-numeric character which is randomly determined.
