Patent number: 11645381Abstract: A tool for providing a user configured one-time password. Responsive to receiving a request for a one-time password, the tool sends the one-time password, based at least in part, on a user configured one time password rule. The tool receives a user configured one-time password return value for the one time password. The tool determines whether the user configured one-time password return value satisfies the user configured one-time password rule when applied to the one-time password. Responsive to a determination that the user configured one-time password return value satisfies the user configured one time password rule, the tool accepts the user configured one-time password return value and granting access to the application.Type: GrantFiled: December 11, 2020Date of Patent: May 9, 2023Assignee: International Business Machines CorporationInventors: Nader M. Nassar, Tamer Nassar, John E. Moore, Jr., John Yow-Chun Chang

Patent number: 10454949Abstract: Cross-Site Request Forgery attacks are mitigated by a CSRF mechanism executing at a computing entity. The CSRF mechanism is operative to analyze information associated with an HTTP request for a resource. The HTTP request typically originates as an HTTP redirect from another computing entity, such as an enterprise Web portal. Depending on the nature of the information associated with the HTTP request, the HTTP request may be rejected because the CSRF mechanism determines that the request is or is likely associated with a CSRF attack. To facilitate this determination, the approach leverages a new type of “referer” attribute, a trustedReferer, which indicates that the request originates from a server that has previously established a trust relationship with the site at which the CSRF mechanism executes. The trustedReferer attribute typically is set by the redirecting entity, and in an HTTP request header field dedicated for that attribute.Type: GrantFiled: November 20, 2015Date of Patent: October 22, 2019Assignee: International Business Machines CorporationInventors: Lewis Lo, Ching-Yun Chao, Li Yi, Leonardo A. Uzcategui, John Yow-Chun Chang, Rohan Gandhi

Patent number: 9426155Abstract: A cloud deployment appliance (or other platform-as-a-service (IPAS) infrastructure software) includes a mechanism to deploy a product as a “shared service” to the cloud, as well as to enable the product to establish a trust relationship between itself and the appliance or IPAS. The mechanism further enables multiple products deployed to the cloud to form trust relationships with each other (despite the fact that each deployment and each product typically, by the nature of the cloud deployment, are intended to be isolated from one another). In addition, once deployed and provisioned into the cloud, a shared service can become part of a single sign-on (SSO) domain automatically. SSO is facilitated using a token-based exchange. Once a product registers with a token service, it can participate in SSO. This approach enables enforcement of consistent access control policy across product boundaries, and without requiring a user to perform any configuration.Type: GrantFiled: April 18, 2013Date of Patent: August 23, 2016Assignee: International Business Machines CorporationInventors: Ching-Yun Chao, John Yow-Chun Chang, Paul W.

Patent number: 9288214Abstract: An authentication and authorization plug-in model for a cloud computing environment enables cloud customers to retain control over their enterprise information when their applications are deployed in the cloud. The cloud service provider provides a pluggable interface for customer security modules. When a customer deploys an application, the cloud environment administrator allocates a resource group for the customer's application and data. The customer registers its own authentication and authorization security module with the cloud security service, and that security module is then used to control what persons or entities can access information associated with the deployed application. To further balance the rights of the various parties, a third party notary service protects the privacy and the access right of the customer when its application and information are deployed in the cloud.Type: GrantFiled: June 30, 2014Date of Patent: March 15, 2016Assignee: International Business Machines CorporationInventors: David Yu Chang, Messaoud Benantar, John Yow-Chun Chang, Vishwanath Venkataramappa
