Abstract
A security apparatus includes an encryptor configured to visually encrypt a target object, and a decryptor configured to decrypt an area corresponding to a decryption gesture in the encrypted target object, during a predetermined period of time.
Claims22
A security apparatus comprising:
- an encryptor configured to
- set a mode of the security apparatus to be an encryption mode, in which encryption gestures are recognized, or a normal mode, in which encryption gestures are not recognized,
- receive, from a user, an encryption gesture directed to a target object,
- determine whether the security apparatus is in the encryption mode or the normal mode,
- upon determining that the security apparatus is in the normal mode, ignore the encryption gesture, and
- upon determining that the security apparatus is in the encryption mode, visually encrypt the target object according to the encryption gesture;
- and
- a decryptor configured to
- detect an input decryption gesture indicating an area in the encrypted target object, and
- decrypt the area for a length of time, wherein the length of time is based on a speed of the decryption gesture,
- wherein the encryptor is further configured to, upon expiration of the length of time, re-encrypt the decrypted area.
8 more elements
A terminal device comprising:
- an encryptor configured to visually encrypt a target object by mixing a noise object to the target object, wherein a mixing ratio of the noise object to the target object is adjusted based on a speed of an encryption gesture directed to the target object;
- and
- a transmitter configured to transmit the encrypted target object to another device,
- wherein the encrypted target object is decrypted for a length of time based on a speed of a decryption gesture, and
- wherein, upon expiration of the length of time, the decrypted target object is re-encrypted.
2 more elements
A terminal device comprising:
- a receiver configured to receive an encrypted target object from another device;
- and
- a decryptor configured to
- detect an input decryption gesture indicating an area in the encrypted target object,
- wherein the decryption gesture is detected when one of a gaze gesture, a drag gesture, a sliding gesture, or a touch gesture is input simultaneously with a continuous touch gesture to a predetermined area on a display of the terminal device, and
- decrypt the area for a length of time, wherein the length of time is based on a speed of the decryption gesture,
- wherein, upon expiration of the length of time, the decrypted area is re-encrypted.
4 more elements
A security method comprising:
- setting a mode of a security apparatus to be an encryption mode, in which encryption gestures are recognized, or a normal mode, in which encryption gestures are not recognized;
- receiving, from a user, an encryption gesture directed to an object displayed on a display;
- determining whether the security apparatus is in the encryption mode or the normal mode;
- upon determining that the security apparatus is in the moral mode, ignoring the encryption gesture;
- upon determining that the security apparatus is in the encryption mode, visually encrypting the object based on the encryption gesture to the object;
- decrypting the encrypted object based on a decryption gesture to the encrypted object for a length of time, wherein the length of time is based on a speed of the decryption gesture;
- and
- upon expiration of the length of time, re-encrypting the decrypted object.
