Abstract
The utility model discloses an anti-peeping dynamic token which includes a dynamic token body and an anti-peeping film. The anti-peeping film is arranged on a display screen of the dynamic token body. The anti-peeping dynamic token can avoid or reduce the possibility that a password displayed on the display screen of the dynamic token is peeped by someone, thus improving the security of the dynamic token and protecting the legal rights and interests of a holder of the dynamic token from being infringed.
Description
Technical field
The utility model relates to the dynamic token technology, is specifically related to a kind of anti-dynamic token of peeping.
Background technology
Authentication is the important step of information security system, and its purpose is to confirm the authenticity and the legitimacy of user identity, and allows validated user within authority, to visit according to system authorization; The refusal disabled user.
Identity identifying technology divides static password authentication, dynamic cipher verification and biological characteristic authentication (fingerprint, iris etc.).It is also the most general the earliest that the static password authentication is used, because of static characteristic, exist be prone to steal, be prone to conjecture, shortcoming such as be prone to break a religious precept, be applicable to the Verification System that safe class is lower.
Dynamic password is also claimed one-time password (one time password is called for short OTP), and its main feature is that password changes (normally changing once in one minute) at any time, and a password can only use once in real time.Therefore, dynamic password can be avoided being reused, guessing and crack, and becomes the most promising authentication techniques at present, is widely used in fields such as ecommerce, finance.
Dynamic token is the hardware unit that is used to produce dynamic password, mainly comprises MCU, clock crystal, display screen, battery and part input unit.During use, dynamic password is displayed on the display screen of dynamic token for use, and password might be peeped like this, has certain potential safety hazard.
The utility model content
The technical problem underlying that the utility model will solve is, a kind of anti-dynamic token of peeping is provided, and reduces or when avoiding dynamic token to use the possibility of peep of cipher.
For solving the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind ofly anti-peep dynamic token, comprise dynamic token body and peep-proof film, said peep-proof film is arranged on the display screen of said dynamic token body.
In one embodiment, said peep-proof film is mounted on the display screen of said dynamic token body.
The beneficial effect of the utility model is: through the peep-proof film is set on the display screen of dynamic token, thereby can reduce or avoid dynamic token to use the time, the possibility of peep of cipher.
Description of drawings
Fig. 1 is the dynamic token structure chart of a kind of embodiment of the utility model.
Embodiment
Combine accompanying drawing that the utility model is done further explain through embodiment below.
As shown in Figure 1, the anti-dynamic token of peeping of the utility model embodiment comprises peep-proof film 1 and dynamic token body; Wherein the dynamic token body comprises housing 21 and is arranged on the display screen 22 on the housing 21.Peep-proof film 1 is arranged on the display screen 22.
The mode that peep-proof film 1 is arranged on the display screen 22 has multiple.For example, can adopt mounting method, peep-proof film 1 is mounted on the display screen 22; And for example, can adopt vacuum coating technology, 1 plating of peep-proof film is installed on the display screen 22.
Because peep-proof film 1 is to utilize in the physical optics polarisation principle to process; After this peep-proof film 1 is set; Implementation method: this diaphragm has used physical optics polarisation principle technology; The screen that sticks this diaphragm only has front and side 30 degree with interior visuality, and from about sides beyond 30 degree, then can't see screen content clearly.Thereby the password that can effectively stop to be shown on the display screen of dynamic token by others peep maybe.
The password that shows on the dynamic token display screen can avoided or reduce to the utility model by the possibility that other people peep, and promoted the fail safe of dynamic token, protected dynamic token holder's legitimate rights and interests not encroached on.
Above content is the further explain that combines concrete execution mode that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
Claims (2)
1. prevent peeping dynamic token for one kind, it is characterized in that comprise dynamic token body and peep-proof film, said peep-proof film is arranged on the display screen of said dynamic token body.
2. dynamic token as claimed in claim 1 is characterized in that, said peep-proof film is mounted on the display screen of said dynamic token body.
