A payment object service receives a request from a giver to associate a payment amount to an object. The request includes one or more images of the object and recipient information, which the payment object service uses to determine whether the association between these images and the information is unique. If the association is unique, the payment object service updates a database to associate the payment amount to the object and enable redemption of the payment amount. When the payment object service receives a request to redeem at least a portion of the payment amount, the payment object service may use one or more images and recipient information obtained from the request to verify that the images and information together correspond to the object. Once the redemption is complete, the payment object service may update the database to specify the current remaining payment amount.

Method, medium, and system for associating a payment amount with a physical object

A certificate manager allows a particular entity such as an individual computer system, computer application, or network service, to define a customized set of rules that are used to identify digital certificates that are trusted by the particular entity. When a digital certificate is presented to the entity, the certificate manager determines whether the digital certificate is trustworthy by examining the characteristics of the certificate such as the expiration of the certificate, the characteristics of the certificate authorities that signed the digital certificate, or the signing algorithms used to generate the digital signatures on the certificate. The certificate manager may be combined with trusted root CA stores, pinned certificate stores, and other certificate management systems to define a customized set of potentially trusted certificates based on the characteristics of the particular entity.

Identification of trusted certificates

A first computer is selected for testing. Information sent from a second computer system to the first computer is intercepted. The information is modified to be noncompliant with a communication protocol, thereby producing noncompliant information. A determination is made whether the first computer device has failed to provide a particular response to receipt of the noncompliant information, and an operation is performed based at least in part on the determination.

Security verification by message interception and modification

Entities of an organization may have difficulties generating and remembering strong passwords. A password management service may generate passwords with high entropy and aid entities in remembering generated passwords. The password management service may generate a list of passwords based on a seed value provided by the entities. The entities may then select a password from the list of passwords to be used at the entities' password. Furthermore, the entities may be allowed to save the list of passwords to aid the entities in remembering their selected password from the list of passwords.

Assisted password generation

Techniques for maintaining potentially compromised authentication information for a plurality of accounts may be provided. An individual piece of authentication information may be associated with one or more tags that indicate access rights with respect to requestors that also provide and maintain other potentially compromised authentication information. A subset of the potentially compromised authentication information may be determined based on the one or more tags in response to a request from a requestor for the potentially compromised authentication information. In an embodiment, the subset of the potentially compromised authentication information may be provided to the requestor.

Compromised authentication information clearing house

The present disclosure provides computer-implemented systems and processes for determining and analyzing a user review status for a first item purchased or otherwise selected by a user; automatically and periodically monitoring review statutes for various alternative items, which may include competing, substitute, or replacement items relative to the first item; and generating an item recommendation based at least in part on a determination of which alternative items may be more positively rated than the first item. When a determination is made that an alternative item may be earning more positive feedback than the first item of interest, the system notifies the user that a possibly better item is available. Candidate alternative items may be identified based on the user's browsing history, groups of related items, or other sources. Candidate items may be weighted based on various attributes of the reviews, including average rating, number of ratings, number of reviews, and type.

Service for notifying users of item review status changes

Techniques for maintaining and updating authentication information for a plurality of accounts may be provided. In an example a first set of authentication information for the plurality of accounts may be maintained. A second set of authentication information that has been marked as potentially compromised may be received. A third set of authentication information may be generated based on the overlap between the first set of authentication information and the second set of authentication information. The first set of authentication information may be updated based at least in part on one or more security authentication protocols and the third set of authentication information.

Authentication information update based on fraud detection

Techniques for marking or flagging an account as potentially being compromised may be provided. Information about the popularity of passwords associated with a plurality of accounts may be maintained. In an example, an account may be marked as potentially being compromised based at least in part on the information about the popularity of passwords and a password included in a request to change the password associated with the account. A notification indicating that an account has been marked as potentially compromised may be generated.

Password-based fraud detection

Data security is enhanced by injecting insecurity into communications between two computer systems to test one of the computer systems. The insecurity is injected by modifying the communications between the two computer systems by modifying or adding messages. A response from one of the computer systems is monitored to determine whether the computer system reacts to the modification in a secure manner or if mitigating actions need to be performed.

Techniques are described for identifying security credentials or other sensitive information by creating a dictionary of data elements included in documents such as source code files, object code files, or other types of files. The data elements may be identified for inclusion in the dictionary based on parsing the documents for delimiter characters, and based on the context of the data elements within the documents. The data elements may also be identified through an entropy-based analysis to detect portions of the documents exhibiting a high degree of entropy compared to a baseline entropy for the documents. The dictionary may be used in a dictionary attack against various systems to determine whether any of the data elements included in the dictionary enable access the systems. The data elements that enable access may be designated as sensitive information hard-coded into the documents.

Dictionary generation for identifying coded credentials

Techniques are described for identifying security credentials or other sensitive information based on an entropy-based analysis of information included in documents such as source code files, object code files, or other types of files. A baseline information entropy may be determined for one or more documents, indicating a baseline level of randomness for information in the document(s). One or more of the documents may be analyzed to identify the presence of high entropy portions that have an information entropy above a threshold value. The threshold value may be based on the baseline information entropy, or based on other criteria such as a programming language of the document(s). Because security credentials may have a higher level of information entropy than the surrounding code, any high entropy portions of the document(s) may be identified as potential security risks.
