Patent number: 10069627Abstract: Electronic devices are adapted to generate cryptographic keys from one or more biometrics. According to one examples, an electronic device can obtain a non-encoded bit string associated with biometric information for an individual. The non-encoded bit string can be treated as if it were encoded and a decoding operation may be applied to the bit string, resulting in a modified bit string. One or more cryptographic keys can then be generated based at least in part on the modified bit string. Other aspects, embodiments, and features are also included.Type: GrantFiled: July 2, 2015Date of Patent: September 4, 2018Assignee: QUALCOMM IncorporatedInventors: Michael William Paddon, Miriam Wiggers De Vries, Philip Michael Hawkes, Craig Brown, Guilherme Luiz Karnas Hoefel, Craig William Northway

Publication number: 20160345165Abstract: Methods, systems, and devices are described for wireless communication to enable data collection from wireless devices in an efficient manner. An aspect of the data collection approaches described herein may involve determining a smaller group of wireless devices from which to collect data. Determining the group may be performed such that the data collected is representative of the wireless devices as a whole. For example, a statistically significant group of wireless devices may be selected to be statistically representative of the wireless devices of the network. Various criteria may be identified for selecting the group. Such criteria may include a specified technique for selecting wireless devices for the group.Type: ApplicationFiled: May 22, 2015Publication date: November 24, 2016Inventors: Guilherme Luiz Karnas Hoefel, Brian Fink, Michael William Paddon, Craig Brown, Vitor Carvalho

Patent number: 9129135Abstract: Systems, methods, devices, and computer program products are described for controlling access to electronic applications by a user. A request may be received (e.g., from a user) to access an electronic application. The availability of points, credits, or time for the particular user may be determined, and access to the electronic application granted or denied based on the determination. User identity may be verified through biometric data, with such verification repeated at periodic or random intervals. Access may be restricted based on a permission level of a particular authority that has responsibility for all or a portion of the user's activities during a particular time period. Access may also be restricted based on the location of the user at the time of the access request.Type: GrantFiled: August 16, 2011Date of Patent: September 8, 2015Inventors: Guilherme Luiz Karnas Hoefel, Hugo Swart, Khaled Helmi El-Maleh, Luis Mirabal

Publication number: 20130047260Abstract: Methods, systems, devices, and computer program products are described for controlling access to electronic content. Content ratings for electronic content are received from each of a number of reviewers, and the input value for each of the reviewers is weighted. Content analysis for the electronic content is also received on each of a number of factors, and each factor is weighted. These weightings may be based on community standards, be specific to a geographic region, or be personalized. The weighted content ratings and the weighted content analysis may be combined to generate an access metric. Access to the electronic content may be controlled based on the access metric.Type: ApplicationFiled: August 16, 2011Publication date: February 21, 2013Applicant: QUALCOMM IncorporatedInventors: Guilherme Luiz Karnas Hoefel, Hugo Swart, Khaled Helmi El-Maleh, Luis Mirabal

Patent number: 8175567Abstract: Techniques to search for signals while in an out-of-service state are described. In an aspect, a network entity may collect information for wireless devices within a designated area, determine at least one search parameter (e.g., a scan rate) based on the collected information, and provide the search parameter(s) to wireless devices within the designated area. The wireless devices may perform searches for signals in accordance with the search parameter(s) when they are out of service. In another aspect, a wireless device may collect information related to out-of-service events encountered by the wireless device, send the collected information to the network entity, receive the search parameter(s) from the network entity, and perform searches in accordance with the search parameter(s) when out of service.

Publication number: 20110235592Abstract: Techniques for allowing network terminals to lease resources from one another. In an exemplary embodiment, an owner terminal determines the availability of resources (locally available or remotely accessible) to share with other terminals. The owner terminal establishes service and price level terms for sharing its resource, and advertises those terms to other terminals. A user terminal determines its own resource requirements, and searches a network for one or more owner terminals offering the desired resource. An owner terminal and a user terminal negotiate on the terms for use of an identified resource, and the owner terminal leases the resource to the user terminal. Applications include a virtual data center for leasing file storage space, network traffic bandwidth leasing to devices such as mobile phones, ad hoc distributed computing architectures, and third-party operating system (OS) support schemes.Type: ApplicationFiled: March 26, 2010Publication date: September 29, 2011Applicant: QUALCOMM IncorporatedInventors: Guilherme Luiz Karnas Hoefel, Kirk Steven Taylor, Liren Chen
