A system for querying a state of aggregate N or creating a projection comprises an interface and a processor. The interface is configured to receive request to query the state of the aggregate N or to create a projection up to a target event and receive a client key. The processor is configured to rehash each event input data of the aggregate N with its corresponding sequence number and a prior event signature to generate a hash value; reencrypt the hash value using the client key to create a check signature; determine whether the check signature is equal to the prior event signature; in response to each check signature being equal to the prior event signature, replay the events of the aggregate N to generate and provide the state of the aggregate N; and in response to a check signature not being equal to the prior event signature, indicate that the aggregate N is not valid.

Methods and systems for authenticating users based on user application activities are described herein. One or more questions and one or more answers may be generated and stored based on a history of user application activities associated with a user. The one or more questions and one or more answers may be generated randomly, and may relate to one or more other users. A request for access to a service may be received. Based on the request, a question associated with the history of user application activity may be selected and presented to the user. A candidate answer may be received from the user, and the user may be authenticated based on comparing the candidate answer to an answer associated with the question presented.

The present innovative solution solves the problem of managing secure documents so that they can be verified, and protected from tampering and illegal printing. A legal document is converted to a secure document by embedding into the legal document one or more security codes that have been encrypted with a standard of proprietary cryptographic algorithm. The security codes are supplemented by a QR code associated with the archive location of each page of the secure document, and stored at a server or database. The security codes stored in the document and can be printed together with the document, as a form of watermark, using UV-sensitive ink or toner at a security printer. The security codes are encrypted and can be printed on varying locations in the secure document pages, which are defined in a geolocation template, separately transmitted in encrypted format.

A system and method of remotely enabling and disabling the starting of one or more vehicles using hardware components installed within a case and a data processing device (DPD), such as a smart phone, in logical communication with one of the vehicle and the case via a WAN, wherein an ignition request is relayed via the WAN to server which parses the ignition request into one or more encrypted ignition instructions, each encrypted ignition instruction sent to a separate vehicle exclusively associated with the encrypted ignition instruction.

Various implementations relate to controller in a system, including: a device connected to a network; and a secure sub-system connected to the device via a first wired connection, the secure sub-system configured to: establish a trusted channel with a user certificate authority (CA) via a provisioning device; receive application parameters from user CA; provision a timestamp or secure time server information based upon the timestamp or secure time server information received from the user CA; create a device identity for the device; and terminate the trusted channel after provisioning the timestamp or secure time server information and creating the device identity for the device.

Novel tools and techniques are provided for implementing monitoring and detection of fraudulent or unauthorized use in telephone conferencing systems or voice networks. In various embodiments, a computing system might monitor call activity through telephone conferencing system or voice network. In response to detecting use of the telephone conferencing system or voice network by at least one party based on the monitored call activity, the computing system might identify incoming and/or outgoing associated with a call initiated by the at least one party. The computing system might analyze the identified incoming and/or outgoing call data to determine whether the call initiated by the at least one party constitutes at least one of fraudulent use or unauthorized use of the telephone conferencing system or voice network. If so, the computing system might initiate one or more first actions.

A system and method for trigger-based scanning of cyber-physical assets, including a distributed operating system, parameter evaluation engine, at least one cyber-physical asset, at least one crypt-ledger, a network, and a scanner that detects trigger conditions and events and performs scans of cyber-physical assets based on the trigger and any relevant stored scan rules before storing scan results as time-series data.

A security platform employs a variety techniques and mechanisms to detect security related anomalies and threats in a computer network environment. The security platform is “big data” driven and employs machine learning to perform security analytics. The security platform performs user/entity behavioral analytics (UEBA) to detect the security related anomalies and threats, regardless of whether such anomalies/threats were previously known. The security platform can include both real-time and batch paths/modes for detecting anomalies and threats. By visually presenting analytical results scored with risk ratings and supporting evidence, the security platform enables network security administrators to respond to a detected anomaly or threat, and to take action promptly.

Disclosed are methods, systems, and non-transitory computer-readable media for determining a trust score associated with a user, comprising detecting entities near a user device operated by the user; calculating the trust score for the user based on a policy that incorporates data about the entities near the user device, the trust score being a score that is indicative of a trust worthiness of data received from the user device, wherein trusted entities near the user device result in an increased trust score, and untrusted entities near the user device result in a decreased trust score; and permitting access to a resource when the trust score is above a threshold.

A network access control system includes a communication device and an authorization system. The communication device is configured to communicate time-critical messages through a time-sensitive network during scheduled time windows. The communication device is further configured to be communicatively connected to a candidate device and to receive a network access request from the candidate device while blocking the candidate device from communicating through the time-sensitive network. The authorization system is communicatively connected to the communication device and configured to authorize the candidate device via a multi-factor authentication protocol that requires a user of the candidate device to successfully provide multiple identification factors. In response to the authorization system authorizing the candidate device, the communication device is configured to grant the candidate device restricted access to one or more of send or receive approved messages through the time-sensitive network.
