Systems and methods for providing directory support in an organization are described. A method, according to one implementation, includes gathering digital data from multiple sources within an organization. The method also includes indexing the digital data in a table that includes at least a first column including names of a plurality of members of the organization and a second column including keywords attributed to the plurality of members. Also, the method includes training a Machine Learning (ML) model by data crawling through the digital data, assigning weights to the keywords, and storing the weights in a third column in the table. In response to receiving an inquiry from a user, the ML model is configured during inference to use information in the table to provide an output to the user identifying a member in the organization who demonstrates expertise on a specific topic.

Systems and methods are provided for enabling peer-to-peer communications using web browsers. A user device, according to one implementations, comprises a processor, a network interface, a network accessing agent, and a client certificate. For example, the client certificate is issued subsequent to validating an identity of a user of the user device. The network accessing agent enables the user device to access a network via the network interface. Also, the client certificate enables the network accessing agent to form a trusted peer-to-peer link with another network accessing agent of a remote user device having another client certificate validating an identity of another user of the remote user device. Furthermore, the trusted peer-to-peer link enables the network accessing agent to securely transfer data files directly to the other network accessing agent of the remote user device while bypassing third-party file-sharing platforms.

Systems and methods are provided for embedding information regarding carbon emissions, carbon offsets, and carbon offset credits into a digital certificate, such as an X.509 certificate. According to one implementation, a method includes a step of computing an environmental account balance for an organization, where the environmental account balance is defined as a difference between offset credits and environmental deficits. For example, the offset credits represent countermeasures by the organization to offset negative effects of emissions of environmentally harmful gases. The environmental deficits represent emissions of environmentally harmful gases for which the organization is liable. Furthermore, the method includes a step of creating a digital certificate for the organization reflecting information pertaining to the environmental account balance.

Systems and methods for analyzing online content are provided. In one implementation, a method includes a step of evaluating an online article to derive credibility information, wherein the online article includes textual and/or graphical content that is accessible via one or more content-sharing platforms. The method also includes a step of adding the credibility information to metadata associated with the online article such that the credibility information is viewable by an end user when the online article is accessed.

Systems and methods for a blockchain-based OCSP responder using smart contracts and custom URI scheme for certificate revocation management. Various embodiments include, responsive to a requirement to determine status of a digital certificate, obtaining blockchain information from the digital certificate; interacting with a specified blockchain network based on the blockchain information; and determining a status of the digital certificate based on the Interacting.

Systems and methods are provided for authenticating a user to enable a user device to gain access to a user account on a secure website. A user authentication method, according to one implementation, includes a step of capturing multiple facial images of a user associated with the user device and user account. The user authentication method further includes a step of comparing the multiple facial images with a sequence of pre-stored facial expressions. Upon detection that the multiple facial images adequately match the pre-stored facial expressions, the user authentication method also includes a step of providing an instant digital certificate to the secure website for gaining access to the user account.

A constrained device includes a processor; and memory storing program code that is configured to cause the processor to, responsive to a requirement for a private key for a function, perform operations on a plurality of seeds to obtain the private key; store the private key in the memory; and utilize the private key for the function. The program code is further configured to cause the processor to, subsequent to the function, remove the private key from the memory. The private key is for a quantum-safe algorithm. Advantageously, the present disclosure supports longer private keys for the quantum-safe algorithm, relative to existing algorithms, with limited resources in the constrained device.

Features are disclosed for a security seal indicating a security of an application. A computing device can receive a request to implement a security seal for an application. The computing device can identify dynamic authentication information and inject the dynamic authentication information into a security seal based on validating a relationship between the application and an entity. The computing device can communicate the security seal to a client device for association with an application. When implemented, the security seal may display a plurality of faces. A face of the plurality of faces may be injected with the dynamic authentication information.

Systems and methods for watermarking machine learning training data for verification thereof, include, for a training data provider, obtaining training data; responsive to verifying the training data based on a use case or application associated therewith, watermarking the training data by adding watermarked data therein; and publishing the watermarked training data. For a machine learning model provider, the systems and methods include obtaining training data to train the machine learning model for an application or use case, to any of make predictions, inferences, and classifications related to the application or use case; obtaining a one-way function associated with the application or use case; checking the training data with the one-way function to determine validity thereof; and, responsive to the validity, utilizing the training data to train the machine learning model.

Systems and methods for utilizing X509 certificates for granting access, such as for location tracking access, physical location access, access to digital content, and the like, include receiving a request for access from a requestor, wherein the request includes one or more of a time, a time period, a location, and a type of access, wherein the access is one of access to a user's location on a user device, access to a physical location, and access to content controlled by the user; issuing a certificate to the requestor based on the request, wherein the certificate includes the time period; one of allowing the requestor to perform the access until expiration of the time period and revoking the certificate prior to the expiration thereby preventing the access.
