Abstract

<P>PROBLEM TO BE SOLVED: To prevent easy guess of a password from display content or selecting operation by a third person when a password is inputted for personal authentication via a touch panel, a pointing device, or an alternative means. <P>SOLUTION: After characters or images to be selected are substituted with alternative figures, the alternative figures are moved/rearranged at random, and then, selected. In this way, reading of the password by a peeping by a third person can be prevented. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、タッチパネルやポインティングデバイスまたは代替手段を用いて個人を認証するためのパスワードを入力する際に、第三者が表示内容や選択操作から容易にパスワードを推測できないようにする技術に関する。  The present invention relates to a technique for preventing a third party from easily guessing a password from display contents and selection operation when inputting a password for authenticating an individual using a touch panel, a pointing device, or an alternative means.

表示装置に表示された複数の選択肢（番号、文字、画像等）を、タッチパネルやポインティングデバイスまたは代替手段を使用して選択することによりパスワードの入力を行う方式がある。この方式は近くにいる第三者が選択肢の表示内容と選択操作を観察することにより容易にパスワードを推測することができるため、選択肢を表示装置に表示する際にランダムに配置することで容易に選択操作からパスワードを推測することができないようにするなどの工夫が見受けられる。  There is a method of inputting a password by selecting a plurality of options (numbers, characters, images, etc.) displayed on the display device using a touch panel, a pointing device, or an alternative means. In this method, a nearby third party can easily guess the password by observing the display contents and selection operation of the options, so it is easy to arrange the options randomly when displaying them on the display device. Some ideas can be found such that the password cannot be guessed from the selection operation.

従来の技術では、第三者が表示装置に表示された複数の選択肢を目視できる視線を確保し、選択操作を観察することにより、ランダムに選択肢を配置した場合においても容易にパスワードを推測することができる。  With the conventional technology, it is possible to easily guess a password even when randomly arranging options by securing a line of sight that allows a third party to view a plurality of options displayed on the display device and observing the selection operation. Can do.

表示装置に表示された複数の選択肢（番号、文字、画像等）の中から対象を選択する直前に、表示された複数の選択肢それぞれに相当する位置に代替図形を表示させることにより元の選択肢が見えない状態にする。認証対象者は選択肢の中から選択予定の位置に表示される代替図形の位置を短期的に記憶する。この時点で代替図形を認証対象者が目で追うことができる速度でランダムに移動させることにより認証対象者は代替図形を目で追い続ける。一定時間が経過すると代替図形はランダム位置にて移動を停止する。認証対象者は目で追い続けてきた選択予定の文字や画像に相当する代替図形を選択する。選択予定の文字や画像を事前に知らない第三者は、ランダムに移動し再配置された選択肢を目で追うことができない特性を利用するものである。  Immediately before selecting a target from among a plurality of options (numbers, characters, images, etc.) displayed on the display device, the alternative option is displayed at a position corresponding to each of the displayed options. Make it invisible. The person to be authenticated memorizes the position of the substitute graphic displayed at the position to be selected from the choices in the short term. At this point, the subject of authentication keeps following the substitute graphic with the eyes by randomly moving the substitute graphic at a speed at which the subject of authentication can follow the subject. After a certain period of time, the substitute graphic stops moving at a random position. The person to be authenticated selects an alternative figure corresponding to the character or image to be selected that has been followed with eyes. A third party who does not know the character or image to be selected in advance uses the characteristic that the option that is randomly moved and repositioned cannot be followed.

一連の選択行為を観察していた第三者は、選択した代替図形または画像が移動前にどの位置にあり、どのような番号、文字、画像であったかを推測するためには、移動前の表示内容と、移動中の各々の代替図形がどのように移動したかを総合的に把握していなければならないため推測が極めて困難になる。  A third party who was observing a series of selection actions would be able to determine which position, number, text, and image the alternative figure or image was selected before moving. Since it is necessary to comprehensively grasp the contents and how each substitute graphic being moved has moved, it is extremely difficult to guess.

本発明は、タッチパネルやポインティングデバイスまたは代替手段により暗証番号やパスワードを入力する際に、第三者に一連の選択行為を観察された場合においても暗証番号やパスワードが盗まれる可能性を大幅に低減できる。  The present invention greatly reduces the possibility that a personal identification number or password will be stolen when a third party observes a series of selection actions when entering the personal identification number or password using a touch panel, pointing device or alternative means. it can.

Claims (2)

認証対象者が記憶した認証のためのパスワードに相当する複数の文字や画像を表示装置に表示させ、タッチパネルやポインティングデバイスまたは代替手段を用いて選択する直前に代替図形に置換えた後に選択を行うことにより、認証対象者が選択した文字や画像をもとに第三者がパスワードを容易に推測できないようにするための装置。  Displaying multiple characters and images corresponding to the password for authentication memorized by the person to be authenticated on the display device, and making a selection after replacing with a substitute figure just before selecting using a touch panel, pointing device, or alternative means This prevents the third party from easily guessing the password based on the characters and images selected by the person to be authenticated. 請求項１に加え、選択予定の文字や画像に相当する位置に代替図形を表示する際に、代替図形の位置をランダムに移動させ、認証対象者に目で追わせた後に選択予定の文字や画像に相当する代替図形を選択させることにより、認証対象者が選択した文字や画像をもとに第三者がパスワードを容易に推測できないようにするための装置。  In addition to claim 1, when the substitute graphic is displayed at a position corresponding to the character or image to be selected, the position of the substitute graphic is moved at random, and the character to be selected or An apparatus for preventing a third party from easily guessing a password based on characters and images selected by the person to be authenticated by selecting an alternative graphic corresponding to an image.
