20140041005 | METHOD AND SYSTEM OF LOGIN AUTHENTICATION - A method and system for login authentication is disclosed. The method comprises the steps of: sending, by a first client, a first login request to a login server and receiving a mapping relationship between original characters and post-mapping characters returned by the login server according to the first login request; and sending, by a second client, a second login request to the login server according to the mapping relationship, with the second login request including post-mapping information corresponding to user information determined according to the mapping relationship. The solution in the present invention is to realize joint login by two clients, such that even if one of the clients is infected with a computer virus, no particular user information can be obtained through the infected client. Thus, the security of login authentication and the security of user information can be improved. | 02-06-2014 |
20140146643 | METHOD AND SYSTEM FOR IMPLEMENTING NEAR FIELD COMMUNICATION - Disclosed are a method and a system for implementing near field communication (NFC). The method includes: modulating a digital signal to generate an audio signal with a transmitting device by utilizing a binary frequency shift keying modulation scheme; playing the generated audio signal with the transmitting device; receiving the audio signal by a receiving device; sampling the audio signal by the receiving device; and demodulating the sampled audio signal for obtaining the digital signal by the receiving device. The present disclosure is capable of implementing NFC between mobile communication devices not having NFC chips equipped, thereby solving the problems that hardware requirements which utilize schemes of the NFC standard are higher, and current application ranges are narrow. | 05-29-2014 |
20150120527 | SYSTEM AND METHOD FOR MANAGING LEASE OF PROPERTIES - A method for managing leases of properties to different users is performed at a computer server. The computer server receives a lease initiation request from a client device, the lease initiation request including a property location identifier and a user identifier. After identifying the property, the computer server determines whether the property is available for lease. If so, the computer server instructs a property control device to release the property, updates a lease record for the property, and sends a lease initiation message to the client device, the lease initiation message including an identifier of the lease record. After receiving a lease termination request from the client device, the computer server causes the property control device to repossess the property, updates the lease record to reflect that the property is available for another lease, and sends a lease termination message to the client device. | 04-30-2015 |
20150120552 | METHOD, DEVICE AND SYSTEM FOR INFORMATION VERIFICATION - The present application discloses methods, devices and systems for information verification, and in particular for multi-user verification for transactions such as online payment transactions. An online account, such as a payment account, can be registered as a multi-user verification account, which requires at least two users to verify a transaction. After receiving a verification request from a first user, a server verifies first verification information (e.g. voiceprint information) from the first user and second verification information (e.g. voiceprint information) from the second user, so that the server may approve or deny the pending transaction in accordance with a comparison of the first and second verification information against respective verification information stored in association with the multi-user verification account. | 04-30-2015 |
20150121469 | METHOD AND DEVICE FOR INFORMATION TRANSMISSION - A method and device for transmitting product information using ultrasonic signals are disclosed. The device detects local availability of ultrasound-encoded product information while the device is at a location in proximity to an ultrasound transmitter. In response to detecting the local availability of the ultrasound-encoded product information, the device requests a user permission from a user of the device to capture the ultrasound-encoded product information. Upon obtaining the user permission to capture the ultrasound-encoded product information, the device receives, from the ultrasound transmitter, an ultrasonic signal encoded with a message containing respective information associated with a respective product. The device decodes the ultrasonic signal to obtain the message in a human-perceivable form. | 04-30-2015 |
20150121544 | ACCOUNT MANAGEMENT METHOD AND ASSOCIATED APPARATUS AND SYSTEM - A method, apparatus and system for securely managing account information are disclosed. In some embodiments, the method is performed at a computer system having one or more processors and memory for storing programs to be executed by the one or more processors. The method includes receiving a request associated with an account. The request includes location verification information. The method includes retrieving, in response to the request, information of a set of predefined locations associated with the account. The method also includes comparing information of the set of predefined locations with the received location verification information to determine whether the received location verification information satisfies a predefined condition. The method further includes sending a response to the request to a destination associated with the account when the received location verification information satisfies the predefined condition. The response includes confidential information associated with the account. | 04-30-2015 |
20150186014 | Information Input Method, Account Information Input Method And Terminal - An electronic device for receiving an account identifier is described. The device includes display; one or more processors; and memory storing one or more programs. The device displays a user interface that includes an area for receiving an account identifier and a first set of candidates for a first set of characters. The device detects a selection of a first candidate of the first set of candidates. In response, the device displays characters in the first candidate in the area. The device, subsequent to detecting the selection of the first candidate, receives a manual input of each character in one or more sets of characters; and displays, in the area, characters in the one or more sets of characters concurrently with at least the characters in the first candidate. A corresponding method and a computer readable storage medium storing one or more programs for execution by the electronic device are also described. | 07-02-2015 |
20150186994 | METHOD, TERMINAL, SERVER AND SYSTEM FOR INFORMATION REGISTRATION - A method and associated terminal, server, and system for information registration, especially payment account registration processes involving payment transactions, are disclosed. By scanning tangible information carriers such as a driver license and credit cards, a client terminal such as a smart phone can generate an image that is sent to a registration server. The registration server can extract user identity information and payment account information from the image. After verifying that the user identity information is associated with a payment account, the registration server generates a registration code for the user and sends the registration code to the client terminal and a bank server. The bank server can then establish corresponding relationships between the registration code, a terminal identifier for the client terminal, and the payment account so that later payment requests from the client terminal can be processed more efficiently and securely. | 07-02-2015 |
