Publication number: 20040193915Abstract: A server interacts with a sender to form a package which can include one or more attached data files to be sent to one or more recipients, and the server applies a policy established by a policy authority of the sender to the package. Since the sever both forms the package through interaction with the sender and applies the policy, any violations of the policy by the package can be brought to the sender's attention during an interactive session with the sender and before encryption of all or part of the package. As a result, the sender is educated regarding the policy of the sender's policy authority, and the sender can modify the package immediately to comport with the policy. The server delivers the package to the one or more intended recipients by sending notification to each recipient and including in such notification package identification data, e.g., a URL by which the package can be retrieved.Type: ApplicationFiled: March 1, 2004Publication date: September 30, 2004Inventors: Jeffrey C. Smith, Jean-Christophe Bandini

Publication number: 20040153645Abstract: Secure web-based messaging according to a “push” paradigm is augmented by specific, intended recipient authentication. In particular, a document can be sent to a specified, intended recipient through the Web using e-mail recipient notification, and the recipient is authenticated prior to delivering the document to the recipient. Such authentication prevents a cracker from snooping a delivery notification e-mail message and retrieving the document prior to retrieval by the true intended recipient. In addition, such authentication of the recipient is driven by the sender such that prior participation by the recipient in the messaging system according to the present invention is required.Type: ApplicationFiled: January 23, 2004Publication date: August 5, 2004Inventors: Jeffrey C.

Patent number: 6651166Abstract: A sender driven certificate enrollment system and methods of its use are provided, in which a sender controls the generation of a digital certificate that is used to encrypt and send a document to a recipient in a secure manner. The sender compares previously stored recipient information to gathered information from the recipient. If the information matches, the sender transfers key generation software to the recipient, which produces the digital certificate, comprising a public and private key pair. The sender can then use the public key to encrypt and send the document to the recipient, wherein the recipient can use the matching private key to decrypt the document.Type: GrantFiled: April 9, 1998Date of Patent: November 18, 2003Assignee: Tumbleweed Software Corp.Inventors: Jeffrey C.

Publication number: 20030101271Abstract: A document delivery architecture dynamically generates a private Uniform Resource Locator (URL) to distribute information. Each private URL (“PURL”) uniquely identifies an intended recipient of a document, the document or set of documents to be delivered, and (optionally) other parameters specific to the delivery process. The intended recipient of a document uses the PURL to retrieve the document. The server, upon retrieval of the document, customizes the behavior of the retrieval based upon attributes included in the PURL, as well as log information associated with the retrieval in a data base. This architecture and usage of PURLs enables secure document delivery and tracking of document receipt.Type: ApplicationFiled: December 30, 2002Publication date: May 29, 2003Inventors: Jeffrey C.

Patent number: 6502191Abstract: A method and system sends documents from a desktop computer inside an intranet through a series of firewalls and/or proxy servers to a server residing on the Internet. A computer in an intranet system protected by a firewall or proxy server uses a software application to access the Internet. The software also encodes binary data to be sent as text. This binary data may be subdivided into smaller text packets. The text packets are sent, using HTTP, to a server outside the firewall, which has been configured to accept such text packets. The server converts the text packets back to the original binary data representation. The binary data, once resident on the internet server, can then be forwarded directly to other internet servers, internet desktop computers, printers, or fax machines.Type: GrantFiled: February 14, 1997Date of Patent: December 31, 2002Assignee: Tumbleweed Communications Corp.Inventors: Jeffrey C. Smith, Jean-Christophe Bandini

Publication number: 20020199095Abstract: A e-mail relay provides message filtering services to an e-mail network. The e-mail relay monitors incoming communication and intercepts e-mail messages. The e-mail relay compares attributes of the messages to data derived from SPAM messages, which is stored in a SPAM database. The e-mail relay restricts the delivery of message based on the comparison such as by restricting the delivery of messages having attributes close to those of SPAM messages from the SPAM database. The SPAM database is constructed by responding to user or administrator indications as to whether received messages are SPAM messages.Type: ApplicationFiled: May 22, 2002Publication date: December 26, 2002Inventors: Jean-Christophe Bandini, Daryl Odnert, Dmitry Dolinsky

Patent number: 6385655Abstract: A method and apparatus are provided for securely delivering documents over an electronic network while preserving document formatting. The invention also provides security that restricts access to the system to an authorized user. A document is sent from a sending computer to a dedicated server, using a send client application. The document is specified for delivery within the send client application, or by clicking and dragging the document onto an appropriate window or icon on the sending computer desktop, or is specified from within a document authoring application. A dedicated server stores the document and forwards an electronic notification to a receiving device. The stored document is downloaded from the dedicated server, using a receive client application, in response to the notification. The receive client application permits the recipient to receive, view, print, and/or manipulate the document.Type: GrantFiled: October 2, 1997Date of Patent: May 7, 2002Assignee: Tumbleweed Communications Corp.Inventors: Jeffrey C.

Patent number: 6119137Abstract: A document delivery server dynamically customizes the format of a document to be delivered, based on the capabilities of the recipient and the type of document to be delivered. The server enables transparent delivery of formatted documents, regardless of the capabilities of the recipient. For example, the recipient platform could be a desktop computer, a network computer, a printer, a fax machine, or a personal digital assistant. The server attempts to maintain the information contained in the document in a high level representation and defers the decision of when to convert to a lower level representation, thereby maximizing the potential set of options and function at each step in the delivery process.Type: GrantFiled: January 30, 1997Date of Patent: September 12, 2000Assignee: Tumbleweed Communications Corp.Inventors: Jeffrey C.

Patent number: 6061448Abstract: A method and system are provided for secure document delivery over a wide area network, such as the Internet. A sender directs a Delivery Server to retrieve an intended recipient's public key. The Delivery Server dynamically queries a certificate authority and retrieves the public key. The public key is transmitted from the Delivery Server to the sender. The sender encrypts the document using a secret key and then encrypts the secret key using the public key. Both encrypted document and encrypted secret key are uploaded to the Delivery Server, and transmitted to the intended recipient. The intended recipient then uses the private key associated with the public key to decrypt the secret key, and uses the secret key to decrypt the document. In an alternative, equally preferred embodiment of the invention, the sender uses the public key to encrypt the document. In yet another embodiment, the server transmits the document to the Delivery Server for encryption.Type: GrantFiled: April 1, 1997Date of Patent: May 9, 2000Assignee: Tumbleweed Communications Corp.Inventors: Jeffrey C.
