The invention provides methods and apparatus for detecting when an online session is compromised. A plurality of device fingerprints may be collected from a user computer that is associated with a designated Session ID. A server may include pages that are delivered to a user for viewing in a browser at which time device fingerprints and Session ID information are collected. By collecting device fingerprints and session information at several locations among the pages delivered by the server throughout an online session, and not only one time or at log-in, a comparison between the fingerprints in association with a Session ID can identify the likelihood of session tampering and man-in-the middle attacks.

A computer receives a request for protected user data with an access token presented by a client as authorization for the client to access the protected user data in a delegated environment. The computer parses the request to create a device fingerprint identifying the device submitting the request for the client. The computer compares the device fingerprint of the request to a previously stored device fingerprint of an authorized device associated with the access token. The computer automatically determines whether to identify the access token as potentially misappropriated based on the comparison of the device fingerprint of the request to the previously stored device fingerprint.

A method for incrementally fingerprinting a computing device includes steps for executing device-identification code programmed to retrieve a complete set of device configuration metrics from a web browser of the computing device, interrupting execution of the device-identification code after retrieval of a first subset of the device configuration metrics, generating a partial device fingerprint from the first subset, generating a temporary device identifier from the partial device fingerprint, and generating a subset indicator identifying the device configuration metrics that compose the first subset. Additional steps include writing the temporary device identifier and the subset indicator to browser-based storage of the computing device, resuming execution of the device-identification code, querying the browser-based storage for presence of the temporary device identifier, and retrieving, responsive to detecting the temporary device identifier, a second subset of the device configuration metrics, the second subset comprising device configuration metrics not identified by the subset indicator.

Methods and systems disclosed herein may be used to determine if licensed software has been previously installed or used on a device by monitoring an identifier associated with the device on which the licensed software is to be installed or used. Prior to operation of licensed software, a client device requires authorization from a license server. The license server may retrieve a unique identifying device fingerprint from the client device to authorize installation of the software based on a probabilistic comparison of the identifier with stored device identifiers subject to a license. If the comparison yields a match and if total instances of retrieval of the retrieved device fingerprint does not exceed licensed rights, the authorization is granted.

The invention discloses a network flow fingerprint feature two-stage multi-classification Internet of Things device identification method, belongs to the technical field of Internet of Things device access control, and the algorithm extracts network flow features from network flow and matches and identifies accessed Internet of Things devices. The algorithm mainly comprises the following steps: firstly, acquiring N pieces of network message data when an Internet of Things device starts an access stage, and extracting features from three dimensions of sequence field contents, sequence protocolinformation and sequence statistical values to serve as device fingerprint features; using a one-to-many multi-classification machine learning architecture to perform preliminary identification on theto-be-detected Internet of Things device; and if a plurality of identification results appear in the preliminary identification, inputting the results into a maximum similarity comparison module forsecondary classification identification, and selecting the type with the highest similarity as a final identification result. According to the method, the problem that identification overlapping is easy to occur when the existing identification algorithm is used for identifying the Internet of Things device is solved, and the identification accuracy and uniqueness are improved.

Techniques described herein relate to using a unique session tracking value that is associated with a web browsing session to correlate a later transaction with a device fingerprint for a user device. The unique session tracking value may be generated via a web page that is being browsed by a user. While the user is browsing, a device fingerprint for the user device may be generated, and the unique session tracking value is stored in association with the device fingerprint, in various embodiments. Later, when a user attempts a transaction, the unique session tracking value can be transmitted via the website so that a service provider can retrieve the device fingerprint, which can be used in assessing a risk of fraud for the transaction.
