摘要： Methods and systems for digital hot wallet protection are provided. A payment channel is established via a Layer-2 network of a cryptocurrency blockchain for transferring a cryptocurrency balance from a first digital wallet of a service provider to a second digital wallet of a trusted entity over a plurality of commitment transactions. A transaction receipt for each commitment transaction is transmitted to the trusted entity via a secure communication channel previously established between the service provider and the trusted entity outside of the Layer-2 network. A transaction log of the service provider is modified so that it no longer represents the current transaction state of the payment channel Responsive to detecting a breach of the first wallet, a transaction is broadcast to a Layer-1 network of the blockchain for transferring the total cryptocurrency balance from the first wallet to the second wallet.

摘要： Methods and systems described herein may implement blockchain cryptocurrency transactions in a variety of environments. An online transaction processor may provide operations for cryptocurrency conversions. The transaction processor may detect that a user is involved in a cryptocurrency transaction with another entity, which is requested to be processed using an amount of cryptocurrency and using an off-chain amount of the cryptocurrency. The transaction processor may determine that the entity does not have a digital wallet, node, or the like on a layer two network to receive and/or process the off-chain balance for the cryptocurrency. The transaction processor may then, after a risk assessment, determine that the user may access the amount of the cryptocurrency from an on-chain balance available to a digital wallet of the cryptocurrency. The transaction processor may make that on-chain amount available and may request repayment via the user's off-chain balance.

摘要： A computer system associates one or more actions with an emoji. The computer system detects a selection of the emoji within an electronic communication by a user. In response to the detecting the selection of the emoji within the electronic communication, the computer system initiates performance of at least one action of the one or more actions based on determining that one or more contextual factors associated with the electronic communication satisfy a set of conditions associated with the at least one action.

摘要： There are provided systems and methods for actionable insight into user interaction data. A service provider server can access user interaction data associated with an interaction between a first communication device and the service provider server, and generates feature representations of the user interaction data, in which the feature representations respectively correspond to extracted features that include textual data features or audio data features. The service provider server can determine an intent of the interaction from the feature representations using a machine learning-trained classifier, in which the intent corresponds to a first actionable insight category. The interaction is mapped to a first cluster based on the intent, and the service provider server issues a remedial action for the interaction based on the mapping of the interaction to the first cluster, in which the remedial action is associated with a particular type of activity in the first actionable insight category.

摘要： Techniques are disclosed relating to methods that include a process, executing on a computer system, receiving a request to access a website, and altering the request to include one or more characteristics of anti-malware scanners. The method further includes the process sending the altered request to the website, and receiving a response to the altered request. The method also includes the process detecting whether the received response utilizes one of a known set of anti-malware cloaking techniques, and providing, based on the detecting, an output indicative of an outcome of the altered request.

摘要： Methods and systems are presented for detecting malicious webpages based on dynamically configuring a device to circumvent one or more evasion techniques implemented within the malicious webpages. When a known malicious webpage is obtained, programming code of the known malicious webpage is analyzed to determine one or more evasion techniques implemented within the known malicious webpage. The one or more evasion techniques may cause a webpage classification engine to falsely classify the known malicious webpage as a non-malicious webpage. A software update is generated based on one or more feature parameters extracted from the one or more evasion techniques. The software update is used to for modify the webpage classification engine such that the webpage classification engine would correctly classify the known malicious webpage.
