According to one embodiment, a method, computer system, and computer program product for CAPTCHA image generation and verification is provided. The embodiment may include generating a first set of attributes. The embodiment may also include generating an image from the first set of attributes. The embodiment may further include generating a plurality of attribute options where the plurality of attribute options comprises at least one attribute within the first set of attributes. The embodiment may also include displaying the generated image with the plurality of generated attribute options. The embodiment may further include prompting a user to select the at least one attribute from the plurality of generated attributes depicted in the displayed image. The embodiment may also include receiving a user selection based on the prompt. The embodiment may further include, in response to the received user selection being correct, verifying the user is a human.

CAPTCHA image generation and verification based on attributes

Systems, methods and/or computer program products for improving autonomous vehicle operation by enabling communication between the autonomous vehicles and BCI systems publishing signals from nearby pedestrians. Wearable BCI devices worn by pedestrians analyze brainwave signals and classify the brainwave signals in order to filter out signals that are unrelated to crossing the street or the directionality of travel by the pedestrian. BCI devices publish, or broadcast brain wave signals related to crossing the street or directionality of travel to the surrounding area where autonomous vehicle receive and process the brainwave signals being published. The autonomous vehicles predict movements of nearby pedestrians based on the intended direction of travel signified by the collected brainwave signals, and the autonomous vehicles select driving actions in response to the anticipated movements of nearby pedestrians.

Brain-computer interface enabled communication between autonomous vehicles and pedestrians

A method includes receiving a security profile comprising user-defined rules for processing sensitive data, and identifying a plurality of sensitive data components in a data file according to the security profile. The method further includes generating a respective format-preserving token for each of the identified plurality of sensitive data components. The method additionally includes generating a corresponding token key for each of the respective-format preserving tokens, and replacing each of the plurality of sensitive data components in the data file with the respective format-preserving token. Further, the method includes cryptographically camouflaging each of the token keys using a first password and storing each of the cryptographically camouflaged token keys.

Restricting access to sensitive data using tokenization

A restriction request message, including a restriction parameter for a secondary account, is received from a device that is associated with a primary account, via a network node that is outside of a secure authorization network. A replenishment request message, including a password and an account replenishment parameter for the secondary account, is also received via a network node that is outside of the authorization network. Authentication is performed based on the password, and the restriction parameter for the secondary account is identified responsive to receiving the replenishment request message. Responsive to determining that the account replenishment parameter satisfies the restriction parameter, a replacement key is generated and associated with the account replenishment parameter for the secondary account. A replenishment response message including the replacement key is transmitted to a device that is associated with the secondary account, via a network node that is outside of the authorization network.

Restricting account use by controlled replenishment

A method for preventing mobile payment is described. The method comprises generating an authorization request, via a payment module, based on sensitive data on a mobile device. The authorization request is transmitted from the payment module to an issuer system. The issuer system sends a neutralization trigger. In response to receiving the neutralization trigger, the payment module is disabled.

System for preventing mobile payment

A method for two factor authentication is described. The method comprises sending an activation code stored on a mobile device to a server for verification. An encrypted secret key generated by the server using the activation code is received. The secret key is decrypted using the activation code stored on the mobile device. The mobile device encrypts the secret key using a predetermined PIN. As a result of a user inputting the predetermined PIN, the secret key is decrypted, the mobile device generates a first token using the secret key and transmits the first token to the server to authenticate the user. After receiving authentication from the server, the information on the mobile device is synced with the server.

Simplified two factor authentication for mobile payments

A method for preventing mobile payment is described. The method comprises receiving an authorization request at an issuer system from a payment module on a mobile device. The authorization request may be based on sensitive data on the mobile device. The issuer system determines whether the mobile device is missing. The issuer system sends a neutralization trigger to the mobile device, and in response to receiving the neutralization trigger, the payment module is disabled.

System and method of neutralizing mobile payment

A method for two factor authentication is described. The method comprises a server receiving an activation code for verification from a mobile device. The server generates an encrypted secret key using the activation code The secret key is encrypted and sent to the mobile device. The server receives a first token generated by the mobile device. The server generates a second token using the secret key, determines whether the first token is identical to the second token, and syncs information with the mobile device.

System and method of mobile authentication

Methods of de-tokenizing secure payment tokens are disclosed. A method according to some embodiments includes receiving a request from an issuer to de-tokenize a secure payment token associated with a transaction conducted using a mobile terminal, generating a metric indicative of a risk of de-tokenizing the secure payment token, comparing the metric indicative of the risk of de-tokenizing the secure payment token to a predetermined threshold, and transmitting a response to the request to de-tokenize the secure payment token, wherein the response is based on the comparison of the metric indicative of the risk of de-tokenizing the secure payment token with the predetermined threshold.
