摘要： Disclosed are systems and methods that facilitate securing communication channels used in a challenge-response system to mitigate spammer intrusion or deception. The systems and methods make use of unique IDs that can be added to outbound messages originating from a sender, a recipient, and a third-party server. The IDs can be correlated according to the relevant parties. Thus, for example, a sender can add a signed ID to an outgoing message. A challenge sent back to the sender for that particular message can echo the same ID or a new ID derived from the original ID to allow a sender to verify that the challenge corresponds to an actual message. The IDs can include cookies as well to facilitate correlation of messages and to facilitate the retrieval of messages once a sender is determined to be legitimate.

摘要： The present invention provides a unique system and method that facilitates incrementally updating spam filters in near real time or real time. Incremental updates can be generated in part by difference learning. Difference learning involves training a new spam filter based on new data and then looking for the differences between the new spam filter and the existing spam filter. Differences can be determined at least in part by comparing the absolute values of parameter changes (weight changes of a feature between the two filters). Other factors such as frequency of parameters can be employed as well. In addition, available updates with respect to particular features or messages can be looked up using one or more lookup tables or databases. When incremental and/or feature-specific updates are available, they can be downloaded such as by a client for example. Incremental updates can be automatically provided or can be provided by request according to client or server preferences.
摘要翻译：本发明提供了一种独特的系统和方法，其便于实时或实时地逐渐更新垃圾邮件过滤器。增量更新可以通过差异学习部分产生。差异学习涉及到根据新数据来培训新的垃圾邮件过滤器，然后寻找新的垃圾邮件过滤器和现有的垃圾邮件过滤器之间的差异。差异可以至少部分地通过比较参数变化的绝对值（两个滤波器之间的特征的权重变化）来确定。也可以使用诸如参数频率的其他因素。此外，可以使用一个或多个查找表或数据库查找关于特定特征或消息的可用更新。当增量和/或功能特定的更新可用时，可以例如通过客户端下载它们。增量更新可以自动提供，也可以根据客户端或服务器的偏好请求提供。

摘要： Disclosed are signature-based systems and methods that facilitate spam detection and prevention at least in part by calculating hash values for an incoming message and then determining a probability that the hash values indicate spam. In particular, the signatures generated for each incoming message can be compared to a database of both spam and good signatures. A count of the number of matches can be divided by a denominator value. The denominator value can be an overall volume of messages sent to the system per signature for example. The denominator value can be discounted to account for different treatments and timing of incoming messages. Furthermore, secure hashes can be generated by combining portions of multiple hashing components. A secure hash can be made from a combination of multiple hashing components or multiple combinations thereof. The signature based system can also be integrated with machine learning systems to optimize spam prevention.
摘要翻译：公开了基于签名的系统和方法，其至少部分地通过计算输入消息的散列值，然后确定散列值指示垃圾邮件的概率来促进垃圾邮件检测和预防。特别地，为每个传入消息生成的签名可以与垃圾邮件和良好签名的数据库进行比较。匹配次数的计数可以除以分母值。分母值可以是例如每个签名发送到系统的消息的总体积。分母值可以折扣，以解决传入消息的不同处理和时间。此外，可以通过组合多个散列分量的部分来生成安全散列。可以从多个散列组件或其多个组合的组合形成安全散列。基于签名的系统也可以与机器学习系统集成，以优化垃圾邮件防范。

摘要： Secure safe sender lists are described. In an implementation, a method includes determining which of a plurality of hierarchical levels corresponds to a message received via a network. Each of the hierarchical level is defined by mechanisms for identifying a sender of the message. The message is routed according to the corresponding one of the hierarchical levels.

摘要： Email spam filtering is performed based on a combination of IP address and domain. When an email message is received, an IP address and a domain associated with the email message are determined. A cross product of the IP address (or portions of the IP address) and the domain (or portions of the domain) is calculated. If the email message is known to be either spam or non-spam, then a spam score based on the known spam status is stored in association with each (IP address, domain) pair element of the cross product. If the spam status of the email message is not known, then the (IP address, domain) pair elements of the cross product are used to lookup previously determined spam scores. A combination of the previously determined spam scores is used to determine whether or not to treat the received email message as spam.
摘要翻译：电子邮件垃圾邮件过滤是基于IP地址和域名的组合来执行的。当接收到电子邮件消息时，确定与电子邮件消息相关联的IP地址和域。计算IP地址（或IP地址的部分）和域（或域的部分）的交叉乘积。如果电子邮件消息被称为垃圾邮件或非垃圾邮件，则根据已知垃圾邮件状态的垃圾邮件分数与交叉产品的每个（IP地址，域）对元素相关联地存储。如果电子邮件消息的垃圾邮件状态未知，则交叉产品的（IP地址，域）对元素将用于查找先前确定的垃圾邮件分数。使用先前确定的垃圾邮件分数的组合来确定是否将接收的电子邮件消息视为垃圾邮件。

摘要： A method and system for determining the reputation of a sender for sending desirable communications is provided. The reputation system identifies senders of communications by keys sent along with the communications. The reputation system then may process a communication to determine whether it is a desirable communication. The reputation system then establishes a reputation for the sender of the communication based on the assessment of whether that communication and other communications sent by that sender are desirable. Once the reputation of a sender is established, the reputation system can discard communications from senders with undesired reputations, provide to the recipient communications from senders with desired reputations, and place in a suspect folder communications from senders with an unknown reputation.

摘要： The claimed subject matter relates to an architecture that can determine costs associated with updating file formats. In particular, the architecture can interface with a network-accessible data storage service in order to determine a cost-benefit to the data storage service for a wide variety of conversion scenarios applicable to the particular topology of the data storage service. For example, the cost-benefit can differ for storage services configured according to a client-server model relative to storage services configured according to a distributed topology. Regardless, the architecture can identify a legacy format, select a converter for converting the legacy format to the updated format, and then determine the cost-benefit for a variety of conversion or migration scenarios.

摘要： A method and system for authenticating that a user responding to a HIP challenge is the user that was issued the challenge is provided. Upon receiving information from a sender purporting to be a particular user, the authentication system generates a HIP challenge requesting information based on the user's identity. Upon receiving a response to the challenge, the authentication system compares the response with the correct response previously stored for that user. If the two responses match, the authentication system identifies the user as the true source of the information.
摘要翻译：用于认证响应HIP挑战的用户被提供给发出挑战的用户的方法和系统。一旦接收到来自发送者是特定用户的信息，认证系统根据用户的身份生成请求信息的HIP质询。在接收到对挑战的响应时，认证系统将响应与先前为该用户存储的正确响应进行比较。如果两个响应匹配，则认证系统将该用户识别为该信息的真实来源。
