CHEXIA-FACE Application

Application to Participate in the NIST Child	Exploitation	Image	

Analytics Face Recognition Evaluation (CHEXIA-FACE)	

1. Who	Should	Participate	

1.1. Biometric identification technology researchers and developers from industry, research institutions, and

academia	are	eligible	to participate	in the Child	Exploitation	Image Analytics Face Recognition	Evaluation –

hereafter referred	to	as the “CHEXIA-FACE”.

2. How	to	Participate

2.1. To request participation	in	the CHEXIA-FACE,	potential	Participants must read this application (Application	

to Participate in the CHEXIA-FACE), sign the “Request	to Participate” section below, attach business cards from

each of the	signing	parties, and send it to the address below (Paragraph 5.8). Signatures of	both the Responsible

Party and the	Point of Contact are	required.

2.1.1. The Responsible	Party is an individual with the	authority to commit the	organization to the	

terms in this document.

2.1.2. The Point of Contact (POC) is an individual with detailed knowledge of the technology applying

for	participation.

2.1.3. In	some	cases,	the	Responsible	Party and the	POC may be	the	same	person.

2.2. Upon receipt of the signed application by the National Institute of Standards and	Technology (NIST), the

organization	will be classified as	a “Tentative Evaluation Participant.” NIST	must receive	this signed application

with the algorithm prototypes. Algorithm prototypes shall be submitted	as Software	Development Kit(s) (SDK).	

They may be submitted during the submission	period	from December 15,	2015 to July 27,	2016. The application

is	required	to	be submitted	with	the first SDK	submission; subsequent submissions	do not require additional

applications.

2.3. It is	the	Government’s	desire	to	select	all	Tentative	Participants	as	Participants.	However, if	demand	for

participation	exceeds the Government’s ability to	properly evaluate the technology, the Government will select

Participants on a	first come	- first	served basis.

2.4. The	CHEXIA-FACE will evaluate detection, recognition,	and	clustering of unconstrained	face in	still	images.

2.5. More information regarding the instructions, input and output formats, and technical specifications for	each

of the above tasks	is	included in	the CHEXIA-FACE:	Concept,	Evaluation	Plan,	and	API available	at

http://www.nist.gov/itl/iad/ig/chexia-face.cfm.

2.6. SDKs	submitted must be compliant with the CHEXIA-FACE protocol and must be	delivered to NIST	(at	the

address in paragraph 5.8 below) during the submission	period	given	in	paragraph	2.2 according to the technical

specifications	given in the CHEXIA-FACE:	Concept,	Evaluation	Plan,	and	API. These require use of strong

encryption.

3. Points	of	Contact

3.1. The CHEXIA-FACE Liaison is	the	government	point	of	contact.		

3.2. All questions and correspondence	should be	directed to the	CHEXIA-FACE Liaison at chexia-face@nist.gov.

CHEXIA-FACE Application

Questions and correspondence will	be	received	by	the CHEXIA-FACE Liaison and other CHEXIA-FACE personnel.

3.3. The	answers to questions and correspondence will be provided	as updates to	the CHEXIA-FACE:	Concept,	

Evaluation	Plan, and API.

3.4. Interested parties and Participants should not contact any individual member of the CHEXIA-FACE staff.

4. Release of CHEXIA-FACE2016 Results

4.1. Interim	results	will	be	provided	to	Participants as a	series of test report cards as described in the CHEXIAFACE:	Concept,	Evaluation	Plan,	and	API. These results will not identify Participants; instead results will be	

associated with random identifiers. The report cards may be provided to Government personnel.

4.2. The Government will release CHEXIA-FACE results in public Final Report(s),	which	will	identify some

Participants alongside their	results:

• The names of Phase 3	Participants will appear in public reports.

• The names of Phase 1	and 2	Participants will appear in public reports also UNLESS	the	participant emails

NIST by July 27, 2016 requesting that their participation is NOT reported. In	that	case	the	quantitative

results will still appear	in the published report	but	without	any attribution	to	the Participants name.

The CHEXIA-FACE Final Report(s) will contain, at a minimum, descriptive information concerning the CHEXIAFACE,	descriptions	of	each	experiment,	and	performance	results.

4.3.	Participants will	be notified of the public release of the CHEXIA-FACE Report(s).	

4.4.	After the release of the CHEXIA-FACE Final Report(s),	Participants may decide	to use	the	results for their

own	purposes. Such	results shall be accompanied	by the following statement: “Results shown	from the Child	

Exploitation	Image Analytics Face Recognition	Evaluation (CHEXIA-FACE)	2016 do	not constitute endorsement of

any particular product by the U.S. Government.” Such results shall	also be accompanied by the Internet address

(URL)	of	the CHEXIA-FACE Final	Report(s) on	the CHEXIA-FACE website.

5. Additional Information

5.1. NIST will use the Participants SDK software only for the agreed-upon	Evaluation,	and in	the	event	errors	are

subsequently found, to rerun prior tests	and resolve those errors. NIST agrees	not	to use the Participants

software for purposes	other than indicated above, without express	permission by the Participant.

5.2. This is a Software	Development Kit (SDK) test. The algorithms will be run	only on	NIST machines by NIST

employees.

5.3.	Software	that is not compliant with the	CHEXIA-FACE protocol specifications cannot	be tested.

5.4.	In	order to	be tested, SDKs	must install easily (i.e., one installation	step	with	no	Participant interaction

required), and shall be executable on any number	of	machines without requiring any machine-specific	license

control procedures	or activation.

5.5.	Participant agrees to hold harmless the CHEXIA-FACE Sponsors, staff, contractors	and all agencies	of the U.S.

Government for any harm or damage incurred in the course of participating in	the CHEXIA-FACE.	

5.6.	The Government is not bound or obligated to follow any recommendations that may be submitted by the

Participant. The	United States Government and individual	agencies	are	prohibited	from, in	any	way, giving	any

special consideration to CHEXIA-FACE Participants or any other party on future	procurements, contracts or

collaborations.

5.7.	By signing this	application,	Participants	acknowledge	that they understand and agree to the provisions of
