Systems and methods for detecting misuse of devices comprising: receiving, from a device, a message comprising a first hash of device data that is indicative of a current device location and usage; generating a second hash of stored data, the stored data being based on an expected location and usage associated with the device; comparing the first and second hashes; and when the first and second hashes do not match, generating an alert.

Systems and methods for detecting device location and usage

Providing a blockchain device enrollment service includes creating an enrollment smart contract that controls access to a service by the device; creating a pools smart contract associated with managing a plurality of different endpoints, wherein the pools smart contract is registered with the enrollment smart contract; registering and configuring a manufacturer smart contract with the enrollment smart contract; and registering and configuring a service provider smart contract with the enrollment smart contract.

Blockchain-based device enrollment service

A communication device sends a Session Initiation Protocol (SIP) INVITE message to establish a call. In response, the call is forked. For example, in parallel forking, the SIP INVITE may be sent to two different communication devices. The forking causes each communication device to send at least one provisional response message. In this case, first and second SIP provisional response messages are received that include Session Description Protocol (SDP) information for a media stream. A first media stream associated with one of the first or second SIP provisional response messages is received and played. A second media stream associated with the other one of the first or second SIP provisional response messages is received within a first time period. In response to receiving the second media stream within the first time period, the first media stream is discarded and the second media stream is played.

Early media handling

The methods and systems of the present disclosure can set at least one threshold for properties of at least one sound, where the at least one threshold comprises a first threshold, and where the at least one sound comprises a first sound received at a first device; monitor changes in properties of the first sound over time at the first device; detect a first violation of the first threshold for the first sound; and provide a first notification based on the detection of the first violation.

Method and system for warning users of offensive behavior

To secure an application, a request to establish a communication session with a client is received from the application, at a server. The server sends the request to establish the communication session to the client. The request to establish the communication session generates a request for a user to approve the application. If the request is approved, a client token is received. A certificate with a public key and a private key is created and the public key is sent to the application. An application token that is encrypted using the public key is received from the application. The application token is unencrypted using the private key and compared to the client token. In response to the unencrypted application token matching the client token, an approval message is sent to the client to establish the communication session. The application can then establish a secure communication session with the client.

Secure application attachment

A first login request of a user is received from a first login window. The first login request comprises a login name, a user identifier, and a challenge. The challenge is generated and received from a second login request to a product in a second login window. The user copies and pastes the challenge into the first login window. A central control system determines if the login name and the user identifier are valid. If the login name and user identifier are valid, a response to the challenge is generated based a private key and is displayed in the first login window. The response to the challenge is copied from the first login window and pasted as part of a second step the second login process. The second login process verifies the response to the challenge using a public key to allow the user access to the product.

Enhanced access security gateway

A first Session Initiation Protocol (SIP) REFER message is sent by an application server to a User Agent (UA). A UA is typically in a communication device, such as a telephone or personal computer. The first SIP REFER message requests the UA to provide a unique Uniform Resource Identifier (URI) for an instance of a networked application. For example, a networked application may be a call recording application. In response to sending the first SIP REFER message, a SIP NOTIFY message with the URI for the instance of the networked application is received by the application server. The application server sends a second SIP REFER message to the UA using the URI. The second SIP REFER message includes information for managing a widget. A widget is object, such as a button or sound. The widget is then displayed or played on a communication device according to a set of rules.

Pushing graphical user interface widgets for communication devices

The system and method detect and properly handle a glare condition in a SIP communication session. A glare condition is where a communication device has two concurrent outstanding requests (typically an incoming and an outgoing request that have not be acknowledged) and needs to process one of the requests before processing the other request. To detect a glare condition, the system and method identify that an out-of-dialog SIP request is received while an outgoing SIP request is pending. In response to detecting the glare condition, a glare algorithm is initiated. The glare algorithm ensures that outstanding requests will be handled in a timely manner.

Mechanisms for handling SIP glare across multiple dialogs

The concept of a secure call indicator is introduced. In general, the secure call indicator is capable of inspecting the security of signaling associated with Session Initiation Protocol (SIP) messages and comparing the security with media descriptions of the actual media path of the SIP messages. Furthermore, the secure call indicator may be configured to indicate the security associated with a communication session via a physical or virtual notification system.
