摘要:
Spammers, and other abusers of web services, may be deterred in their attempts to sign up for these services at large scale by making changes to the service registration procedure, where the changes are designed to break the spammer's infrastructure. In one example, a procedure to register for a web service involves presenting a Human Interaction Proof (HIP, or “captcha”) to the user, and gating access to the service upon receipt of a correct solution. If spammers use botnets and/or image capture techniques to initiate registration processes and to transport the HIPs to human or automated solvers, then the registration procedure can be changed in a way that is incompatible with capturing these images, or in a way that is incompatible with receiving HIP solutions from someplace other than the location at which registration was initiated.

In one embodiment, a human interactive proof portal 140 may control access to an online data service 122. A communication interface 280 may establish a human interactive proof session 600 with a client user 110 by presenting a proof challenge set having multiple proof challenges. A clock 290 may record a challenge response time for each proof challenge. A processor 220 may provide access to an online data service 122 based on the human interactive proof session.
摘要:
A method for generating one or more human interactive proofs (HIPs) is described herein. A HIP request may be received. One of a plurality of HIP engines may be selected using a randomization algorithm. Each HIP engine may have a distinct algorithm for generating the one or more HIPs. The one or more HIPs may be generated using the one of the plurality of HIP engines.

Chewing gum bases, and resultant chewing gums, that are environmentally friendly are provided. The chewing gum base comprises approximately 3 to about 99% by weight poly(lactic acid) copolymers selected from the group consisting of poly(lactic acid-dimer-fatty acid-oxazoline) copolymers and poly(lactic acid-diol-urethane) copolymers.
摘要:
An animal digestible chewing gum composition is provided comprising a water soluble gum portion and water insoluble gum base portion including an animal digestible elastomer. Additionally, a method for creating an animal digestible chew gum is provided comprising the steps of creating a chewing gum base that includes a sufficient amount of an animal digestible elastomer to create a resultant chewing gum that is more digestible by an animal than a chewing gum without such an elastomer, and adding to the chewing gum base a water soluble portion to create a resultant chewing gum.
摘要:

Methods of treating esophageal spasms, dysphagia, and gastroparesis utilizing chewing gum formulations containing sildenafil citrate are also provided.
摘要:
Chewing gum bases, and resultant chewing gums, that are environmentally friendly are provided. The chewing gum base comprising approximately 1 to about 99% by weight polyhydroxyalkanoates having side chain lengths of C4 to C30.
摘要:
The overlay human interactive proof system (“OHIPS”) and techniques described herein operate in conjunction with any known or later developed computer-based applications or services to provide secure access to resources by reliably differentiating between human and non-human users. Humans have a generally superior ability to differentiate misaligned characters or objects from correctly aligned ones. As such, the OHIP splits an image including one or more visual objects into two or more partial images to form a HIP. The partial images may also be further split into groups of sub-partial images, and/or the partial images (or the sub-partial images) may be moved, so that at any given alignment position, a user can recognize only some visual objects. A user is instructed to reassemble the partial images at one or more predetermined alignment positions using a GUI, and the user is asked to identify information regarding one or more visible objects.
