Patent number: 11575634Abstract: Systems and methods for providing location-restricted message exchange include receiving, by a system provider device over a network from a sender device, a location-restricted message that includes sender message information and first location information that is associated with a first location. The system provider device then receives, over the network from a first receiver device, second location information that is associated with a second location. The system provider device then determines that the second location is in a limited geographic message exchange area with the first location and, in response, sends at least some of the sender message information by the system provider device over the network to the first receiver device. They system provider device may use filtering criteria provided by the first or second receiver device and use that filtering criteria to determine whether to send the sender message information to the first or second receiver device.Type: GrantFiled: October 30, 2021Date of Patent: February 7, 2023Assignee: PAYPAL, INC.Inventor: Koson Cao

Patent number: 9749312Abstract: Systems and methods for secure password entry are provided. A request to authenticate a user is received from a user device. A sequence of characters is generated. The sequence has a first subset of the characters selected from a password associated with the user. At least one of the characters appears a different number of times in the sequence than in the password. The sequence of characters is displayed on the user device in response to the request. A user selection of a second subset of the characters in the sequence is received through the user device. The user is authenticated in response to a determination that the first subset of the characters matches the second subset of the characters.Type: GrantFiled: September 30, 2015Date of Patent: August 29, 2017Assignee: PAYPAL, INC.Inventors: Grom Dong, Koson Cao

Patent number: 9178873Abstract: Systems and methods for secure password entry are provided. When a user wishes to log in or otherwise authenticate as an authorized user of a system using a password, the system can provide an apparently random sequence of characters to the user. The user can select all of the characters in the sequence of characters that also appear in the user's password. The system can determine whether all of the selected characters are in the password and that all of the characters in the sequence of characters that are also in the password were selected. The user can select the characters in any order and the selected characters can include less than all of the characters in the password. In this way, the system can authenticate the user without the user entering their entire password, thereby increasing both the efficiency and the security of the password entry operation.Type: GrantFiled: December 18, 2013Date of Patent: November 3, 2015Assignee: PAYPAL.
