Techniques are disclosed relating to methods that include training, by a new profile process executing on a computer system, a contrastive loss function to identify fraudulent images associated with a particular entity. The new profile process may receive new profile information that includes a new profile image and a new profile identifier and compare the new profile identifier to one or more existing profile identifiers. In response to determining that one or more existing profile identifiers satisfy a threshold identifier metric, a particular neural network, using the contrastive loss function, may compare the new profile image to one or more existing profile images corresponding to the one or more existing profile identifiers. The new profile process may determine, using the comparing, whether the new profile information is a possible fake profile of a legitimate profile.

Identification of fraudulent online profiles

Systems and/or techniques for facilitating automatic detection of proxy-based phishing sites are provided. In various embodiments, a system can access a computer-executable web resource and can embed an authorization verification logic within the computer-executable web resource. In various aspects, upon execution of the computer-executable web resource, the authorization verification logic can be configured to: identify a computing domain via which the computer-executable web resource is being executed; compare the identified computing domain with one or more authorized computing domains; determine that the identified computing domain is an unauthorized proxy site if the identified computing domain does not match at least one of the one or more authorized computing domains; and initiate a remedial action based on determining that the identified computing domain is an unauthorized proxy site.

Automatic detection of proxy-based phishing sites

Systems and/or techniques for facilitating relay attack prevention for electronic quick response (QR) codes are provided. In various embodiments, a system can determine a cardinality and a frame rate. In various aspects, the system can transmit a first electronic instruction to a mobile device, which can cause the mobile device to generate a set of interlaced frames having the determined cardinality. In various cases, the set of interlaced frames can respectively correspond to a set of portions of an electronic QR code, such that different frames from the set of interlaced frames depict different portions from the set of portions of the electronic QR code. In various aspects, the first electronic instruction can further cause the mobile device to sequentially render, at the determined frame rate, the set of interlaced frames on an electronic display of the mobile device. In various aspects, this can cause one portion from the set of portions of the electronic QR code to be depicted on the electronic display at a time. In various instances, the system can transmit a second electronic instruction to a point-of-sale device, which can cause the point-of-sale device to reconfigure scanner settings of the point-of-sale device, and which can enable the point-of-sale device to capture the set of interlaced frames sequentially rendered on the electronic display of the mobile device based on the determined cardinality and the determined frame rate.

Relay attack prevention for electronic QR codes

A method for operating a list in a mobile terminal is disclosed. An example method includes displaying a first set of items from an item list in the mobile terminal, changing the item list based on a received command, determining a direction of most recent movement in the item list before the receiving of the command, determining items from the item list to display according to the determined direction and the change of the item list, and displaying the determined items from the item list.

Adaptive determination of information display

A user device comprising: i) transmit path circuitry and receive path circuitry configured to communicate with a payment server; and ii) processing circuitry configured to control the transmit path circuitry and receive path circuitry. The processing circuitry is further configured to: a) receive a user input related to a payment process; b) calculate a risk score indicative of a likelihood of fraudulent activity associated with the payment process, wherein the risk score calculation is based on confidential information associated with the user that is stored on the user device; and c) transmit to the payment server a payment action and the risk score associated with the payment action without disclosing the confidential information. The confidential information comprises personally identifiable information and/or private information of the user. The processing circuitry calculates the risk score using a risk base model received from a model server.

System and method for fraud detection in a mobile device

A telephony collaboration system and method are provided. The method includes activating a wireless feature on an admin device, determining, whether a new group is to be created, determining whether to subscribe a guest device to an existing group, determining whether to join the guest device to a previously subscribed to group, when the admin device is to create the new group, creating the new group and assigning a name to the new group, when the guest device is to subscribe to the existing group, scanning for the existing group and transmitting a subscription request requesting that the guest device be subscribed to the existing group, and when the admin device is to join the previously subscribed to group, scanning for the previously subscribed to group and transmitting a join request requesting that the admin device be registered with the previously subscribed to group.
