Congregation Sharing is an optional feature that can be enabled inside New World Scheduler by a Congregation Administrator. It allows you to automatically share and synchronize all New World Scheduler data with other appointed brothers in your congregation.
Congregation Sharing does NOT store confidential information online. Congregation Sharing is fully compliant with sfl and fully compliant with European Union (EU) General Data Protection Regulation (GDPR).
Congregation Sharing is used by tens of thousands of Jehovah’s Witnesses worldwide, including elders, pioneers, missionaries, Bethelites and even Branch Committee members.
Does the Branch 'approve' of New World Scheduler and Congregation Sharing?
New World Scheduler is not an official app or program created by the Watchtower Society. Therefore, New World Scheduler is obviously not “endorsed by”, “recommended” or “officially approved” by the organisation.
This makes sense. The organisation does not and will not create a list of books, songs, movies, websites, programs or apps we can or cant use. (see w14 7/15 14)
World Headquarters (WHQ) has been in contact with us several times over the years NW Scheduler has been in operation. They are fully aware of New World Scheduler and has no objections to its use, nor any objections to the use of Congregation Sharing.
New World Scheduler and our NW Publisher app are both used by hundreds of thousands of Jehovah’s Witnesses worldwide every single day! This includes elders, pioneers, missionaries, Bethelites and even Branch Committee members.
Please feel free to read the comments of many spiritually mature elders around the world, including in your local area.
Sharing Security and Data Protection
New World Scheduler takes data security and data protection very seriously and ensures your congregation data is fully secure at all times. We fear Jehovah and would never do anything to misuse or endanger your data.
“Prove yourselves cautious as serpents and yet innocent as doves.” – Matthew 10:16
Congregation Sharing has been designed so that your congregation information can only be accessed by approved brothers in your congregation.
This is no way anyone else can ever see or edit your congregation data, including New World Scheduler support personnel or programmers.
Authorization
Congregation Sharing uses OAuth 2.0 authorization, including Access Tokens and Refresh Tokens, to provide secure credentials to approved brothers in your congregation. This means only authenticated users with the correct credentials can access your encrypted data strings.
Secure credentials only allow access to your congregation, meaning authenticated users cannot even access another congregations encrypted data strings.
Two-Factor Authentication (2FA)
Congregation Sharing uses Two-Factor Authentication (2FA). This means in addition to knowing the Sharing Region, Congregation ID and Congregation Sharing Password, a persons Email address is also used to identify and verify they are allowed to connect to the congregation.
A Congregation Administrator will create Person records and enter these brothers Email addresses into New World Scheduler. Next, they add the brothers to Congregation Sharing as Shared Persons.
These brothers can now connect using a 3-step process:
- Connect. The brother must have the correct Sharing Region, Congregation ID and Congregation Sharing Password to connect to your Congregation.
- Identify. They must use their Email to Identify who they are. This must exactly match their Person record.
- Verify. Their computer must be Verified with a Verification Code sent to their Email.
This is very similar to the security processes of jwpub.org and is an extremely secure system.
Data Security
Congregation Sharing implements the following best-practise security processes:
- New World Scheduler uses both data obfuscation and data encryption to ensure any transferred data strings are meaningless unless viewed inside New World Scheduler.
- New World Scheduler uses end-to-end encryption, which means your data is fully secured before it is transferred to other appointed brothers and cannot be opened by anyone outside your congregation.
- New World Scheduler uses 128-bit Encryption Keys generated on your local computer using your Congregation Sharing Password. This means your local data is converted to randomised and meaningless strings before ever leaving your computer.
- Encryption keys are generated locally on your computer and are never transferred. NW Scheduler personal do not have any access to your encryption keys.
- New World Scheduler developers or support personnel do not and can not access your encryption keys or congregation data. It is therefore technically impossible for them to decrypt, view, see or edit your data under any circumstances.
- Data transfer uses HTTPS connections, so it is additionally encrypted on the transport layer (known as TLS).
- The only “data” that ever leaves your local computer are randomised and meaningless strings.
- Each congregation can choose which sharing server they use and where it is located. Data is only ever transferred to and from this one server to approved brothers in your congregation. Data on the sharing server you select is not backed up, saved or transferred anywhere else. Data on the sharing server cannot be accessed by anyone outside of your congregation.
- After selecting a server location, each congregation is assigned a unique and obfuscated storage location to transfer the encrypted data strings. Access to this location is restricted to approved Shared Persons who must first authenticate using your unique Congregation ID, Congregation Sharing Password, 2-Factor Authentication and OAuth 2.0 authorization token.
- If you Disable Sharing, the meaningless encrypted strings are immediately and permanently removed from the sharing server.
Data Encrption
Our data encryption implements the password-based key derivation functionality PBKDF2, by using a pseudo-random number generator based on HMACSHA1.
The Encryption algorithm is Advanced Encryption Standard (AES).
Encryption key length is 128-bit, salt is 256-bits of random entropy, Initialization Vector is 256-bits of random entropy. Derivation Iterations is 2000.
Encryption keys are generated locally on your computer and are never transferred. NW Scheduler personal do not have any access to your encryption keys.
How does Congregation Sharing work?
Here is a real-world example of how Congregation Sharing works:
Elder A
- Elder A opens New World Scheduler on his own computer and schedules a Christian Life and Ministry Meeting part.
- Your local New World Scheduler obfuscates the data so it has no meaning outside of New World Scheduler.
- New World Scheduler encrypts the obfuscated data using a unique encryption key generated by your own computer. This creates a set of seemingly random and meaningless strings.
- New World Scheduler creates a secure connection to your selected transfer server.
- New World Scheduler uploads these randomised strings to your secured congregation folder on the transfer server.
Elder B
- Elder B opens New World Scheduler on his computer. His computer authenticates with the transfer server using the Congregation ID, Congregation Password and his Member PIN.
- If authenticated, his computer creates a secure connection to your congregation folder and checks for any updated strings.
- If any updated strings are detected, they are retrieved from the New World Scheduler transfer server.
- New World Scheduler uses his unique locally generated encryption key to decrypt the randomised strings.
- New World Scheduler interprets the data converting it back into meaningful information.
Does New World Scheduler share data using Email?
No, New World Scheduler does not use Email or a Mail Server to share or transfer data.
We recommend brothers be very cautious about using any program or application that recommends sharing congregation information via email.
For example, KHS recommends sending a ‘Data Exchange’ file via Email to share and synchronise congregation or person data. They state: “KHS users can easily exchange password protected files with each other via e-mail. Exchanging data is simple, easy, and requires less than a minute on both ends.“
Using Email or a Mail Server to transfer data is extremely insecure and unsafe. In fact, it is one of the least secure methods possible. It is extremely irresponsible to share congregation data via email.
We strongly recommend against using Email or a Mail Server to share data files, for at least the following reasons:
- Email and a Mail Server is almost always not encrypted. All data is freely viewable.
- For example, Gmail, Hotmail, Outlook do not use encryption
- Email is by default sent from server to server in clear text that can be read by anyone while in transit.
- Mail Server data can be easily accessed by any Server or Email Admin, at any time.
- For example: Gmail, Hotmail, Outlook have thousands of Server and Email Admins that can access this data.
- Email and Mail Server data is usually permanently kept on a mail server, even if you remember to click Delete.
- For example: Most large companies have data retention policies that require keeping data for many years.
- Most Email and Mail Servers have built-in “backdoor access” for government agencies. This means they can very easily access any data at any time.
- For example, google “Edward Snowden”.
“Email by default is not and was never intended to be a secure mechanism for sending data,” says Dr. Catherine J. Ullman, Senior Information Security Analyst for UB. “Although you need credentials to log in and access the e-mail in your mailbox, email is by default sent from server to server in clear text that can be read by anyone while in transit.”
New World Scheduler does not use Email or a Mail Server to share or transfer data.
Is New World Scheduler web-based? Does it share data via web servers? Can the data be accessed online?
No, New World Scheduler is not web-based. It must be installed locally on your computer.
We recommend brothers be very cautious about using web-based or cloud-based apps (such as Deckhand or Hourglass) to store congregation information. While web-based applications are convenient, we personally feel the direction and principles found in sfl do not permit web-based applications to store congregation data.
Web-based applications (like Hourglass or Deckhand) store all congregation and person data permanently online and do not use end-to-end encryption.
Web-based applications by nature must allow any website administrators, developers and potentially support personnel full access to everyone’s data. This means they can potentially access every single persons data in every single congregation. We do not feel comfortable with this, nor do we feel this complies with the principles and direction in sfl.
Web-based applications are also much more prone to hacking or data theft. They provide a single point for a hacker to attack and obtain every single persons data in every single congregation.
Web-based applications also rely on the honesty and integrity of worldly hosting companies, sometimes located in countries with poor data integrity records.
Web-based applications can even be subject to government or company subpoenas, whereby the software company or hosting company must provide access to everyone’s data.
New World Scheduler is not web based. All data is stored on your local computer, and we use end-to-end encryption. This means your data is truly safe. It cannot be opened or accessed by our developers, support staff, or anyone else.
