It should be noted that above-mentioned application scenarios are only for example, the disclosure is not restricted to this.

Fig. 3 is a kind of flow chart of method for transmitting information shown according to an exemplary embodiment, as shown in figure 3, should The method of information is transmitted for including the following steps in terminal or server.

In step s 11, the key of first terminal corresponding first is obtained.

In the present embodiment, first key is that the first wearable device is defeated according to the mark of the first wearable device and user What the cipher instruction entered generated.

It is readily apparent that, the mark of each wearable device is different, and wearable device identifies according to it and generates key, can be with Two wearable devices are avoided to generate identical key.

Optionally, the first wearable device can be Intelligent bracelet.

It should be noted that the corresponding key of terminal can for the information for being sent to terminal encrypted used in it is close Key (used key is decrypted in the information sent to terminal), or the information sent to terminal carries out encryption institute The key (used key is decrypted to the information for being sent to terminal) used.In the present embodiment, first key is The information for being sent to first terminal is carried out encrypting used key.

In step s 12, specify information is encrypted using first key, obtains the first cipher-text information.

In the present embodiment, the sensitive informations such as the identifying code of payment, the account of bank and password are designated the information as.First is close Literary information is the specify information of ciphertext form.

In step s 13, the first cipher-text information is sent to first terminal.

In the present embodiment, first terminal is used to that the first cipher-text information to be decrypted using the first wearable device.

The embodiment of the present disclosure by obtain first terminal corresponding first key, using first key to specify information into Row encryption obtains the first cipher-text information, and sends the first cipher-text information to first terminal, even if specify information is in the process of transmission Middle to be intercepted and captured by third party, third party also can only obtain the specify information of ciphertext form, can not get real information, effectively avoid The leakage of specify information.

Fig. 4 is the flow chart of the method for another transmission information shown according to an exemplary embodiment, as shown in figure 4, The method of the transmission information is for including the following steps in terminal.

In the step s 21, the first cipher-text information is received.

In the present embodiment, the first cipher-text information is to be added using the corresponding first key of first terminal to specify information It is close to obtain, i.e. the specify information of ciphertext form.First key is mark of first wearable device according to the first wearable device Know and the cipher instruction generation of user's input.Designate the information as the sensitive letter such as the identifying code of payment, the account of bank and password Breath.

Optionally, the first wearable device can be Intelligent bracelet.

In step S22, the first cipher-text information is sent to the first wearable device.

In step S23, specify information is received.

In the present embodiment, specify information is that the first wearable device is solved using the first cipher-text information of third key pair It is close to obtain.Third key is the cipher instruction that the first wearable device is inputted according to the mark of the first wearable device and user It generates.Third key is to make in a pair of secret keys used in rivest, shamir, adelman or symmetric encipherment algorithm with first key The same key.

It should be noted that the corresponding key of terminal can for the information for being sent to terminal encrypted used in it is close Key (used key is decrypted in the information sent to terminal), or the information sent to terminal carries out encryption institute The key (used key is decrypted to the information for being sent to terminal) used.In the present embodiment, first key is The information for being sent to first terminal is carried out to encrypt used key, third key is that the information for sending first terminal carries out Key used in encrypting.

The embodiment of the present disclosure uses third key pair the by receiving the first cipher-text information, and by the first wearable device One cipher-text information is decrypted, and obtains specify information, even if specify information is intercepted and captured by third party during transmission, third party Also it can only obtain the specify information of ciphertext form, real information can not be got, effectively prevent the leakage of specify information.

Fig. 5 is the flow chart of the method for another transmission information shown according to an exemplary embodiment, as shown in figure 5, The method of the transmission information is given first terminal (application scenarios as shown in Figure 1) for server transport specify information, including with Lower step.
