Patent number: 11983143Abstract: A method includes receiving a plurality of files where each file represents an object. The method further combines selected files of the plurality of files into an aggregation file and stores the aggregation file on low-latency storage media, such as disk storage media. The method represents the aggregation file with a single inode that is stored on the low-latency storage media. The method migrates the aggregate file to high-latency storage media, such as tape storage media, while leaving the single inode representing the aggregation file on the low-latency storage media. By collecting files into larger aggregation files, the number of files archived is significantly reduced and the files archived are of larger size. The reduced number of files and increased size of the files improves archival and retrieval performance due to reduced metadata operation overhead. A corresponding system and computer program product are also disclosed.Type: GrantFiled: July 29, 2022Date of Patent: May 14, 2024Assignee: International Business Machines CorporationInventors: Khanh V. Ngo, Slavisa Sarafijanovic, Dominic Mueller-Wicke, Simon Lorenz, Harald Seipp, Takeshi Ishimoto

Patent number: 11979421Abstract: In some examples, a system for decorating network traffic flows with outlier scores includes a processor and a memory device to store traffic flows received from a network. The processor is configured to receive a set of traffic flows from the memory device and generate a tree model to split the traffic flows into clusters of traffic flows. Each cluster corresponds with a leaf of the tree model. The processor is further configured to generate machine learning models for each of the clusters of traffic flows separately. For a new traffic flow, the processor is configured to identify a specific one of the machine learning models that corresponds with the new traffic flow, compute an outlier score for the new traffic flow using the identified specific one of the machine learning models, and decorate the new traffic flow with the outlier score.Type: GrantFiled: December 31, 2021Date of Patent: May 7, 2024Assignee: International Business Machines CorporationInventors: Yair Allouche, Aviad Cohen, Ravid Sagy, Ofer Haim Biller, Eitan Daniel Farchi

Patent number: 11979334Abstract: A system for initiating web containers and isolating network traffic to web containers is described. The system initiates and uses web containers for associated web-based resources, such as domain addresses owned by a single entity. When a web container for a domain address has not been initiated, the system determines an owner of the domain address and any domain addresses associated with the owner and initiates a web container for the domain address and the associated domains. When a user navigates to the domain addresses associated with the determined owner, the system isolates the network activity to the initiated web container.Type: GrantFiled: July 22, 2019Date of Patent: May 7, 2024Assignee: International Business Machines CorporationInventors: Renato Luiz De Freitas Cunha, Ana Paula Appel, Lucas Correia Villa Real, Henrique Von Atzingen Do Amaral

Patent number: 11977625Abstract: A method, apparatus and computer program product to defend learning models that are vulnerable to adversarial example attack. It is assumed that data (a “dataset”) is available in multiple modalities (e.g., text and images, audio and images in video, etc.). The defense approach herein is premised on the recognition that the correlations between the different modalities for the same entity can be exploited to defend against such attacks, as it is not realistic for an adversary to attack multiple modalities. To this end, according to this technique, adversarial samples are identified and rejected if the features from one (the attacked) modality are determined to be sufficiently far away from those of another un-attacked modality for the same entity. In other words, the approach herein leverages the consistency between multiple modalities in the data to defend against adversarial attacks on one modality.Type: GrantFiled: May 12, 2023Date of Patent: May 7, 2024Assignee: International Business Machines CorporationInventors: Ian Michael Molloy, Youngja Park, Taesung Lee, Wenjie Wang
